Temperature Sensitive Fish

[mattsilvester]

Hi All,

Are there certain fish species that are known for being temperature-hardy. I don't mean rapidly fluctuating temperatures, but rather seasonal temperatures; with a bias for "warmer" temperatures.

I've read that lionfish can tolerate temperatures as high as 35C (95f). I would think the highest my tank could get would be about 31-21C (86-88f).

What other fish could be comfortable at that temperature?
