aye the day i came back to lurk;
if you want an african butterfly fish upgrade the tank to about a 40breeder and they will eat larvae along with live mosquitoes and crickets
dont do corys with bettas in a 20gal youll get more use out of autocats or raphs
currently im working on a 500 gallon saltwater tank for a friend and a 250 freshwater tank for either alligator gars/arrowanas/discus
