So I have a 40 Breeder sitting next to me in the basement. Temperature right now is 72°F in the summer time, hottest gets to about 75 maybe, coldest would probably be around 65 then I will most likely have a heater for anything lover than that. But I'm trying not to use a heater.
Option 1: Coldwater River. I am thinking of having 2 canisters shooting from one end to the other. I would probably have white cloud minnows, hillstream loaches and something else. Or something totally different. What are other cold water fish that like a nice current?
Option 2: Just a non river tank. HUGE school of bloodfin tetras, or something similar. I really feel like having a big school of something. I also heard/read that Buenoes aires tetras can tolerate mid sixties?
Option 3: 4 Axolotls
Idk what else to think of. Give me some ideas on fish and tank setups.
No Goldfish, and No Danios.
Thanks
