Cold water fish?

[kaosfere]

MTS is striking.

I'm thinking about setting up a tank at work. The only problem is that heating devices are considered to pose a fire hazard here, and against safety code -- so I'd be limited to coldwater fish.

I'm really not too fond of goldfish. What other coldwater fish are commonly available that would be active and interesting in a 10-20 gallon tank?

paradise fish can be kept at room temperature. they are related to gouramis and bettas. (a betta needs heated water). heterandria formosa, the 'least killifish' is another choice. they are very tiny fish which can easily be kept in a small (under 5g) tank. they would probably get lost in a larger tank. a school of white cloud minnows (maybe half normal color and half albino) and a large-ish snail would be good in a 10-20g tank.

White clouds are a great cool water fish. I have kept mine at 65F before (a cold basement). They can take the heat a bit if you have plenty of water mov't. I would stick to a 20 gallon to get a proper sized school and really see great behaviour from them.

I agree, white clouds and/or hetera. fermosas would be excellent.

I'm also a fan of least killifish but darters will also provide you with great fun. If you need a supplier for darters just let me know.
