How long can fish go without food ?

derv

HI there,

As the xmas is coming up I wil be going away for a few days.

How long can the fish last without food ?
I need to know if I will need to give someone the keys to my house to feed them.

There will be no one in the house for 2 (possibly 3) days.


Thanks

If you trust someone to come in and feed them, I'd do that. See if a neighbor can stop in in the morning, feed/switch light on maybe. Then Stop back by at night time and flip the light off, or second feeding if need be (depends on your cycle I suppose). It's what I do - but there is usually someone here. I like to make sure they know how much to feed as well, just giving a quick rundown, and so you don't come back to a mess....

If not, maybe an auto feeder... But then again they might be ok, and really hungry by the time you get back! *waits to see more answers*

Your fish should be fine for 2 or 3 days without food. Just make sure you feed them before you leave and feed them when you get home.

Should you decide to have someone come in and feed them you can put food portions in those weekly pill containers, that way there's no question of amount.
 

Sasukii

! that's GENIUS Lucy!
 

Lucy

I wish I could take credit for the idea.

When I went away for a few days I used those little paper cups that fast food places provide for ketchup and put a serving in each cup.
All my husband had to do was dump the food in.
 

derv

thanks for the heads up guys.
I don't really trust the neighbours enough to give them the keys
(I have not been living there too long )

so I will probably leave them alone for the 2 days.
 

Lucy

They'll be fine.

Oh! Welcome to Fish Lore.
 

derv

thanks, from looking at the site - looks like I have a lot to learn

Since fish are cold blooded they do not need calories to burn to maintain a constant body temperatue, therefore than can get buy on less food than you would expect.
 

Dozey

All good advice. One other option is that you can buy “weekend feeder wafers”. They are simply hard little disk that will dissolve over a couple of days providing some food to the fish.

The feeder blocks work well, but leave a bit of plaster behind in the tank that can be messy to clean up. Tetra makes a good feeder block that doesn't use plaster, but is slightly more expensive. The problem with it is some fish won't even view it as food... Guess it's trial and error to figure out what feeders you could leave with your fish.
 

dalinturg

I think a waterchange is also recommened before you leave.
 

Butterfly

All good advise Feed them well and then do a good water change and you should be good to go. They will be really happy to see you

derv

thanks for all the info guys. I will be sure to do a water change.
i'm sure I'll have lots more questions in the future.

As you might have seen from my other threads, I think my guppy has Ammonia poisining, which I'm dealing with. But, he won't eat! He completely ignores the food, even though I've been doing 50% water changes every day. How long can he last like this?
 

Alessa

I had a guppy like that... he lasted a week
 

MaddieLynn

Anyone else had any experience with it?
 

Lucy

Was he eating then stopped?
Changing foods might help.
 

sirdarksol

To directly answer the question; many days. Fish don't waste calories on producing body heat, so they don't eat as much for their body weight as us warm blooded critters.

However, with a sick fish, it will be burning calories on trying to heal itself. As Lucy suggested, changing food might help, as might soaking the food in garlic juice. He might also like freeze-dried daphnia.
 

MaddieLynn

Yes, he was eating and then he stopped. He hasn't eaten in at least 4 days. I'm getting worreid about him. I put a Cheerio in the tank, thinking he might nibble on it... but, he doesn't seem interested.

I know I've mentioned this many times before, but his mouth appears to be stuck open and he looks bloated, but I don't think it's dropsy because I don't see any scales sticking out.

The really weird thing is this it looks like he has a hole in the middle of the front of his upper lip! I've never heard of anything like that before.

And a little goos news: The red spot looks a little better.

Anyone ever heard of a fish with a hole before?

I must have missed the part about the mouth being stuck open, bloated and a hole in his lip.
Poor thing.

Check this, see if anything resembles your fish.

Some of the bacterial infections resemble him with the red spot, but I didn't find anything that looks like his lip.
 

prairielilly

I had a harlequin rasbora with a red spot on his side and what looked like a white/clear 'bubble' on his lower lip. After a week the 'bubble' fell off and there was a hole. I never knew what it was, but I did find an article (sorry don't have the ref) that said some fish may develop cysts on their lips. I was terrified it was cotton mouth (I know now it wasn't). The hole/bubble thing didn't seem to bother the fish at all.

He died this morning

I'm so sorry:'(

Sorry to hear that.

I have some Cories and Danios and was wondering how long they can go without food. Cause I just went a week without feeding them. Turkey Day... I feel so bad stuffing myself and they had nothing. . But Christmas Break is coming up and for me that is at most a few days short of a month that I won't be able to tend my fishies.

I was going to set up a 10 Gal to hold them during the break but I'm gonna be away from home most of it. I was thinking about getting those white feeders... I think they make a 14 day one... and then just go without for the other two weeks.

Good Idea?
 

gremlin

As long as they are well fed, they should be fine for a while. You can try a weekend/vacation feeder, but I have no experience with them. If there is any algae in the tank, they will feed off that also. Is there anyone who can tend them while you are gone? At least once a week?
 

fishingman001

depending on the size some fish can go up to 2 weeks without food. A feeder should work but it might make the water messy. It would be better if a person can come over to feed the fish.
 

bolivianbaby

The OP asked a question. He didn't say he was going to, he is searching for information. No reason to be disrespectful.

Apollo, from the information I've gathered, it's usually recommended to not have the fish go without food for more than seven days.

If you brought them home in the 10g, would you be able to to feed them once every seven days? Also, if you brought them home, you'd be able to keep an eye on the water parameters and keep up with your water changes.

Just a few thoughts and I hope this helps!
 

harpua2002

You don't even have to use a tank if it's out of the budget. You can move the filter and heater from your 20 gallon to a Rubbermaid container as a temporary home. I would not recommend leaving fish for a month even with an automatic feeder, but that's JMO.
 

btate617

The not feeding the fish for 7 days or up to 2 weeks, I wouldn't use that for the fish you have. For full grown adult cichlids yes it would work, but not for the fish you have IMO.

Those vacation block feeders are , all they are good for is messing up your water.
The auto feeders may work, but be warned they do malfunction and have been known to dump a ton of food in to the tank and then you have the same problem as using a block feeder.

Like said the best option would be to have someone feed them or find a way to bring them along.

I would also think about the water changes. I know the automatic feeders can drop a bit too much food at times, so the excess food could cause an increase in water parameters. Every thank is different but if there's a chance for the Nitrates to grow above the tolerance level, that should be something to take into consideration too.
 

Meenu

I assume you are in college and are talking about your winter break? for us, the dorms would be locked and not at all accessible.

if this is the situation, nobody will be able to get in to feed them. they will not survive a month with no food. I think bringing them with you in a rubbermaid is probably the best option.
 

couesfanatic

Look at Eheims automatic fish feeder. I have left my fish(danios) for 3 weeks and a few days before and all went well. Eheims fish feeder is much better than the others because the food will not get wet. It has an internal fan to dry the food and it also keeps the food away from the water while being stored. You can also adjust the amount of food it dispenses.

You could risk it, but if I were you I would bring them home and have a parent, sibling or neighbor check on them periodically.

Some people on this website need to calm down. :;bb

I do have an automatic fish feeder in my salon...it feeds our fin babies from sun-mon ..although our fish would be fine, I CHOOSE not to let them go without food..heres a link of the one we have



it has worked great for over 5 years but spend the money on a good quality one..that way you know there's less chance for overfeeding and malfunctions...good luck!

Please refrain from rudeness and help the best of our abilities..thank you!
 

Lucy

Sorry ApolloX54, I know you didn't ask this but it's something you might want to ask about.
My daughter's college takes the opportunity to fumigate the dorms while everyone is gone.

Ok well... some people are very touchy on this subject.

1. I've decided not to bring them home. My water chemistry is different and would cause too many problems. My fish and plants are flourishing at a 6 or below pH... Also seeing how my whole family is going on trips during break. I think it would be worse to go through all the moving and stuff just to have them sit in different water and still not get attention.

2. I live in on campus apt. So random people can't just come in, I know that is the best solution if I had that option.

3. I have a had great experience with the white weekend feeders. Never had a problem with cloudy water or anything. Now the green/brown ones I used once and it didn't dissolve at all. Not even considering automatic feeders.

4. I already have tanks at home, but they are neglected and dirty. I won't have time to clean and properly acclimate.

5. No, I do not believe there is any fumigation going on cause this is my second year here and they do not enter rooms when cleaning anyways.

After looking at the calender again it looks to be only 3 weeks and I know they make 14 days feeders. Whether or not they last that long is up in the air.

ONLY 3 weeks? lol ...that's a bit of time for the fin babies....the link I gave you is an awesome self feeder and won't leave anything leftover in the tank..you can set it to feed as much as needed but not overfeed......the weekend feeders will leave a huge residue in the tank and you won't be there for a good amount of time to change the water....but if you decided to go with the weekend feeders, which by the way only lasts 3-5 days, go with the gel ones..ive never seen a 14 day feeder..that's new to me....the white chalky ones do raise the ph from the substance in the feeder..but none of them will last 3 weeks as far as ive seen... either way, a once a day feeding will be fine for them and not make the water parimeters go nuts like the blocks would...good luck either way
 

crazedACD

I wouldn't so much worry about feeding (vacation feeder should be OK), but more or less something malfunctioning...do they turn the electricity off in the building while everyone's away? I always have a piece of hardware in my tanks going haywire, impellers stop turning, filter motor burns out, heater stops heating...I would really worry without someone there to check. Everyone must leave the dorms during break? Is there a roommate or friend in the building that could come and check?
 

sirdarksol

I second Shawnie's suggestion for the gel feeders (they're not supposed to melt, by the way. The fish just peck at them as they need), and for another reason. The bits of food in them are kind of big, and tend to expand a bit as they get wet. We had a member lose a fish when too many of the pellets were released at once. A molly ate a bunch of them and they expanded in the molly's stomach. That was a particularly confusing death, too, because it almost looked like a pregnancy gone wrong. The gel packs don't have pellets in them, so this can't happen.
 

Meenu

I know they sell the 14 day pyramids at our petsmart and petco.

I am sure I'm going to get flamed for saying this: It sounds like you've already made up your mind. You came and asked for advice, and when every person told you it is a bad idea, you ignored it. You won't even consider an automatic feeder as Shawnie and couesfanatic suggested, like you say in #3 of your post. So if you weren't open to suggestions and had already made up your mind, why bother asking the question? ??? If you were looking for validation, you shouldn't need that from a website of strangers. And if you had started out giving us the entire situation (i.e. the travelling while you are at home, etc.) maybe we could have addressed that too.

Anyway, good luck to you and your fish, good luck on finals, and have an awesome break.

It wasn't really made up until I had a talk with the rents and realized I wasn't gonna be at home for much at all during break. I would have considered an auto feeder if I had money for one. I was legitimately looking for help. This ain't no website of strangers, they helped me many a times especially Shawnie and Lucy. I just hope I can provide the same help some day. Yeah that my bad on the info though again I didn't know at time of first post.

I've heard stories about the pyramids.. the ones I was looking at were big fish. Reviews were decent. Same old same old. Gone in about 10 days. Cloudyish water. Will use again.

So these gels are made to be eaten straight from the package. Maybe my danios just don't like them or something cause when I used that one seemed like it was still just as big. Didn't just it in either. I put a wire through it and hung it so it was at the top. Just for the Danios.

hi, slight problem. I am going on vacation this weekend for about a 9 days. I went to the pet store to pick up a seven day feeder but they only had three day feeders left. So I got a pack of those but I am worried what my fish will do for the remaining days. My tank is a 30 gallon freshwater set up for about 6 months with plenty of plants, duckweed, algae, shrimp etc. Should my fish be ok grazing on algae and duckweed for a while? They're mostly platys, mollys and one bolivian ram.

Are there any tricks to feeding while you're away? Like maybe leave a slab of cucumber somewhere?
 

Jaysee

I don't feed my fish while I'm away. I've gone away for 2 weeks and the fish were fine....it takes a while for them to starve to death.
 

iloveengl

I do not recommend tossing that feeder in your tank. It will more than likely just gunk up the place and cause an ammonia spike. The ones I've tried in years past are just rubbish. Fish don't even like them.

I'm also not a fan of automated feeders. Too hard to adjust small enough amounts, and too many horror stories of the entire contents dropping into the tank.

The best option is to separate 9 days worth of food in a pill box and ask a friend or neighbor to dump each day's worth while you're out. (Or every 2-3 days, however often you feed them.)

If it was my tank, and I was leaving for 9 days, and my friends & trusted neighbors were also leaving for vacation, then I would feed well (but not overfeed) for a few days before I left, and then just let them feed off the duckweed, algae, and whatever else they can find while I was gone. They won't starve to death in that time. Though you may very well lose a few shrimp to the mollies or ram. Actually you could purchase a few more shrimp before you leave just to use as feeders.

Jaysee.

Yeah, what he said.
