We got an angelfish to help break up the territorial black skirt tetras that we have. The angel has helped with this problem but now he spends most of his time acting like a bottom feeder, he was even eating on an algae wafer. Is this normal behavior for them or is he just hungry? We feed our fish flakes every day and have given them blood worms for treats but the angel is constantly on the bottom of the tank picking in the gravel and in the plants for food I'm assuming.
We knew angels were semi aggressive but we thought he would be okay with our group until we get a 55gal going in a few months. The angel is fine with our tetras and the green catfish but his is nipping at our cory catfish. I didn't know angels were much of nippers, but our cory is bigger and slow, which is when the angel comes at him. Will getting another cory cat help or should we just take the angel back to the pet store?
