Ideas for stocking a heater-less 55g?

[Louie]

I keep all my tanks at room temp (72-75 depending on the season) except for the hap tank that I keep at 78. Believe me, my fish do more than survive.

75 degrees I can see but not 70.

Dont you notice a change with your oscar in lets say 70 vs 75?

They are breeding now as are all the cichlids it took weeks of 90 to 98 degrees for them to start spawning.

Now those are heat loving fish lol . Granted the Tropicals breed way cooler.
