What other fish are like Gymno's?

[AOmonsta]

I ask this in the sense of a fish that will do well in low temps in the 50s and 60s for a few months. I had no idea this was the case for gymno's till recently.

I was wanting to use my 150 for a fahaka puffer, but since my tank is in the garage, there is no way I can constantly keep the heat stable, cause it gets cold in there. So I think it'll be perfect for gymno's.

Any other info would be appreciated. Thanks.

Gars can also withstand those temperature drops, although I don't know if any fit in that size tank.
