Fiddler Crabs And Craw Fish

hello I am newly starting to have fiddler crabs and crawfish. I have 4 fiddler crabs and 3 crawfish. I put a bottle with sand in it to give them air. I feed them shrimp pellets, algae discs and fluval bug bites. Is there anything else I should be doing? Thank you for all your help!

 

Give them some blanched spinach, which from that he will ingest calcium for shell conditioning, you can feed almost any cooked veg it's all good stuff for them

 

Ok thank you for the help much appreciated.

 

No doubt PTVinnyMac will be round for a chat hes got the cray bug hard and some nice ones, do your regular water changes as they like good water and they are great escape artists plenty of places to hide

 

Thanks again what size tank do you have? I have a fully enclosed top so hopefully they won’t get out although my fiddler crabs have been trying hard. They settled down since I put an air bottle in the tank.

 

180ltr but min are Australian red claw crayfish they grow to over 10" your ones are band in the uk

 

That’s awesome I haven’t seen them here in the states. So you have a 50 gallon tank mine is a 125 gallon or 2.048 ltr. Thank for your help.

 

He loves to move sand the bird keep an eye on them

 

Hi! Welcome to aquaria. Did you know that while crawfish are freshwater, fiddler crabs require low end brackish water to survive?

 

Yes I do but I tried to talk to some members on here about it and all I got was back lash. Lol

I do have salt in my aquarium for my fiddler crabs and for my angel fish.

I thought this was supposed to be a friendly community?

Fishlore prides itself on being a welcoming and friendly bunch. Please report any rude posts and a mod will come and help.

 

It absolutely is. Part of what makes this forem great is we share knowledge and accept that we all will make errors, accepting knowledge from others helps us all

 

Seeing how I have been doing this for almost 25 years.

This is my first day on this forum. Thank you all.

 

Oh good, then you will have a wealth of knowledge to help others with as well!

 

Lol yes I will !!!

Ask away!!!!!!!!!!

Yes ask away!!!!

Within my knowledge of what I have done with aquariums.

 

So random question...how long can fiddler crabs live outside of water...like if he escaped my puffer tank

 

A fiddler crab can live out of water for months at a time.

 

With 0 access to water or food

 

Yes look it up.

 

Oh nooo I can no longer use my livingroom

 

I can’t say what they will find out of there aquarium in your house but in the wild they can live for months at a time without water.

Lol

Lol. They still have to have access to moisture to wet their gills so they can breathe, but my fiddlers spend about ½ their time out of water.

Sheldon....hes on my floor (potentially) somewhere.....
How longs he got...the boys seemed scared of the 2nd one so I removed him but the thought of him, say, running across me while I sit on the couch terrifys me lol

Well I can’t believe that happened! Terrible! I was just asking because so many pet stores sell them deceivingly as freshwater and fully aquatic. I purchased mine on a whI'm but then went home to do research and found out they need low brackish and access to land. I had to get a whole separate setup for them! lol worth it to see them happy and healthy. One of the most entertains pets, especially when the boy is trying to get the girl’s attention.

I guess that depends on the humidity in the room. If I had to guess I’d say he has maybe a day. I don’t really know though. Was he supposed to be puffer food?

 

Exactly what I was saying but everyone on this website was ridiculing me for it

They need salt but yet when I was in other chat forums they told me I was crazy for adding salt to my aquarium huh

And your a valued member seams like your doing the same thing.

Hey I had a thought on your air bottle. Cool idea, but did you run an airline to run fresh air in?

Yes and the boys were scared and didnt eat him lol

Alot of people add salt to their aquariums for a lot of different reasons
I had only pointed out differences between aquarium salt in a fresh tank vesa true brackish tank (which is what my puffers are in)

 

Hey I had a thought on your air bottle. Cool idea, but did you run an airline to run fresh air in?

Yes I ran a line from my bubbler I think that’s enough

I thought this was super cool...would never thought of it myself

 

Yes

Oh I agree. It’s just how I’ve seen it done a few times so I was wondering.

On the salt, I think the only consideration I would give is to what kind of salt you are using. I think it’s better to use reef or marine salt rather than aquarium salt because it has a lot of needed minerals.

I keep my salinity for my fiddlers at 1.004, what do you keep yours at?

 

The air line to the right goes to my bottle.

 

How did you weigh the bottle down? Did you silicone it to the bottom?

 

This is the salt I am using it is for fresh water only

 

Wow you’ve been keeping fish since you were 11?

 

How did you weigh the bottle down? Did you silicone it to the bottom?

No I have sand in my aquarium so I filled full of sand put my hand over the open end and submerged it and pointed the open end down.

Yea

 

Cool! Me too! Though I’m a few years younger at 33.

I think it would be good to consider switching your salt going forward to the marine salt or reef salt so you get the added minerals. The cost is about the same.

 

I don’t want to hurt my fish. I’ve never tried marine salt.

 

Ok I understand.

 

I wish you would talk to some other members on here all I have gotten is nothing but negativity because I add salt to my fresh water tank it’s nice to talk to someone that knows what they are talking about!

Is marine salt ok for fresh water?
