how is this not a micro fish lol
I brought up a similar thing about Northern Sunfish (about the same max size and similar build) once and the explanation given was that if the fish gets big enough to be caught on standard gear, and is caught easily by those targeting standards, even if it does not reach a pound it would make more sense to be a standard. The micro designation I think is to keep micro-anglers from getting a huge advantage as I think most of us can agree we'd rather have a big river redhorse than five or six notropises. Also micros are really hard to ID and as a lot of them aren't truly ID able from the pics so they get thier own designation. A fish like black acara thats on the border of size and is caught easily by standard anglers seems fair to put on a standard lifelist. Theres a few that might be worth considering elevating to standard like river chub....
that makes more sense. Black acaras do kinda have mouths on the bigger size for what they are. But what about the dusky damselfish? all the other small damselfish that are the same size as the dusky are under micro and dusky damselfish was so hard to catch, like i had to use some of my smallest hooks for it. It has a small body, small mouth, needs small gear, and its hard to ID withe the cocoa and longfin etc
