Angels are probably my second favorite fish right next to cories. This setup even with 4 angels seemed to be just fine. I've never really worked with hatchets but I know they don't really get too big and theyre body structure would make it hard for angels to eat. Other then that keep in mind the more angels you get the more pairs that are possible to form, which means a lot of aggression. Another thing is cories whiskers are pretty much there eye sight so rough bottom tanks can harm cories. Other then that Good luck. Post pictures.I just got a 50 gallon tank and I was wondering if these fish are compatible: 6 hatchet fish, 2 or 4 angelfish, and 4 cory catfish? Also, is that overstocked?
