I have not spent much time on these, but they look good.

This site also has info on what forums are out there, but they show Reddit so who knows. However, shows some forums for specific species/types of fish.

Thanks Daskski, I've heard some really good things about fishlore and tropicalfishkeeping but haven't spent much time on either other than when Google sent me there for answers. I'll check both out.
