My angelfish eat everything! By the time my catfish gets any food the angles have ate all the food! I'm having the same problem with my top dwelling killifish. Is there any special tactics I could use to make sure my catfish gets food and my other guys don't over eat? Btw I mix there food according to day. One day I'll feed them blood worms. The next day granules, then I skip a day. I haven't seen any problem at it signs yet but I just wanted be sure that I'm not going to cause any harm in the near future. Any suggestions would help.
