The RED List of Fish, Inverts, and Corals

[lorenz0]

in all honesty i think most fish shouldn't even be kept in anything under 100gal...

but you guys are talking about fish that need special requirements. Think about all those fish out there that are housed in small tanks (like yellow tangs in 30 gals). Personally i think anything that isn't recognized as a nano fish should be on that list cause most people'd tanks are under 50gal.
