Hi all,

I've been asked by a neighbour to suggest fish for their nano tank, they've had problems with their heater so are looking for coldwater critters for it.
I don't know fully about the size of the tank but as it's nano it is pretty small (I'm assuming too small for a betta). Do you know any fish species they could have? They've said something like rice fish are small enough but apparently lots of different species and I can't figure out another name for them to gather information

I don't think they are suitable for nano tanks....  Nano's are like 2-3gallons right?

Yeah, it's pretty darn tiny. I would suggest shrimp, but they've had shrimp and I don't know of any coldwater ones.
Shall read up on that link though Smiley

Haha might suggest them! Although, I think they'd prefer fish.
They did mention a glass snake tank they had from when they had snakes and it sounded like they still had them. Perhaps I could try to convince them that it'd be easier to make it water tight and have some pretty fish in it - they'd certainly not have the heater problem

If it's at least 5 US gallons I can think of several fish that would work very well in an unheated tank, (down to around mid 60's F anyway).

I would suggest shrimp, but they've had shrimp and I don't know of any coldwater ones.

Most all of the Caridina shrimp, (Crystal Red/Black, Bee, Tiger), prefer cool water.  PFK had an article several years ago about a collection trip to China and most of the shrimp found were in water at around 60F.  I has a German breeder tell me they would tolerate water temps into the 40's, but I never kept them that cold.

He really doubts it's even 2 US gallons as is a tiny tank.
Will have a gander at the shrimp, he said they liked the shrimp, but when the heater broke (turned off), they all died within hours

Horned Nerite Snails apparently do well in unheated tanks and they have the added bonuses of not reproducing and being amazing algae munchers...

They are also pretty small with a max size of about half of an inch in diameter...

Well good luck with that!!!!!  I can only think of a couple fish I'd even consider for a tank that small and then it would require daily attention and just be an accident waiting to happen.

Snails could work

You could always go to his house and accidently break the tank and then smile real pretty.  That might work.

If the tank is 2 gallons or less, it is no longer a nano. It's a micro. On the practical side, I wouldn't even recommend attempting to house and maintain it. If it was at least 5 gals, I could recommend a pair of Scarlet Badis.
