If anyone knows of a fish that dosent need a heater please tell.

No Bettas or goldfish!

Shawnie

betta's need heaters some minnows are ok with air temps but mostly its the wilds that you dont want in your tank like trout, salmon, etc...

SnaKiZe

Pretty much any fish are fine without heaters, but you SHOULD get one, unless where you live it gets under 70 Degrees alot.

Shawnie

I respectfully disagree..."any" fish are not happy with cold temps..hence why the are called "tropicals" they need temps 76-82 depending on the fish

White clouds,amphibians,some gobies,and snails can do fine in a cool water aquarium.

Like Shawnie said,bettas do need heaters.

If it's for the 5 gallon listed in your info,then goldfish aren't an option anyway.Snails or a dwarf frog would be ok. Not many different types of fish for something that small.

If it's for something bigger,your options go up a little bit.

Dwarf frog? do they need a wet and dry tank or just wet or just dry

soldieroffortune1974

Dwarf frogs,are aquatic mostly.They need to be able to surface to breathe,but rarely spend a lot of time on land.

I am talking about the Albino clawed frog,mostly.Mine took over the bottom of my 175 gallon,and would chase my plecos.I have pieces of floating driftwood for them if they choose to get out of the water,but I have never seen them on it.They just swim up,gulp some air and down they go.

Yeah ive had white clouds for a while now and they do fine without a heater. Ive had them in a 10 gal aquarium for about a year and they were happy.Now they are in my 75 gal with a heater and they dont seem to mind that either. Dwarf frogs just need a wet tank. Make sure the surface of the water is not overly turbulent so they can get a gulp of air easily.

Torez

Are ADFs compatible with ghost shrimp and what do they eat?

75galguy

Blood worms and some flake foods but make sure your fish doesnt eat them all before they can get to it.

What size tank are they for?
I have Platys in my 20 gal. I let the temp fall down to 68 so they don't multiply as much. They are still happy, still multiplying, but less. They seem to be doing quite well with room temp.

Torez

So can i get 1 or 2 ADFs for my 5 gal.

Gonna have to disagree on the dwarf frog thing. They may be able to survive at room temp, but the majority of them come from the Congo area, which is tropical. Their water is very likely to be uniformly warm throughout the year.

I agree with SDS.
ADF's should have a heater. They prefer temps around 77-78F

sirdarksol

Thank you. My post may not have been really clear on that.

Tropical fish live in warm waters in the wild so it's best to get one. I spent like $24 dollars on mine and I thought it wold not work but it did.

Guppies?

sirdarksol

Guppies can stand cooler waters, but generally still need warmer water than our home thermostats are set at.

White Cloud Mountain Minnows are among the most well-known temperate fish (outside of goldies, which the poster said are out).

Fish Addict

Why don't you want a heater, since really, they're pretty cheap at a place like Petsmart, and they make it a lot easier...

Lucy

Just to clarify....
African Dwarf Frogs are fully aquatic. They never spend anytime on land but they do need to get to the surface for air.
They dart up, take a gulp and go right back down.

I don't know much about African Clawed Frogs, only that they get big and need at least 15-20g per frog.

Some of the goodeids prefer cooler temps, though not all. And sounds like you're looking for something for a 5 gal? In which case most of them get way too big and mean! Neat fish though! My panther goodeids were in an unheated 20-gal and doing great other than eating all their young which they weren't supposed to (no wonder they're endangered!)
White clouds, which many suggested are very nice cooler water fish... I think there are a few loaches that like cooler temps too, but again, I doubt most of them would go in a 5 gal. I believe some of the killies also do well with cooler temps, but no clue which since I am death to killies no matter what I do it seems.

sirdarksol

And that they will eat smaller fish. I remember a few posts from people who bought these guys not knowing there was a difference between ADFs and ACFs.

NolanCL

Just an FYI - the Clawed Frogs will get fairly large, I think 15-20G per frog is excessive, I would say more around the 10G and you can fudge that if you have a good filter.
They are 100% aquatic and will never get out of the water, well they will escape, but quickly die if left on dry land.
