I want to get some angel fish to put into my planted 60 gal. I have 3 small clown loaches, a senegal birchir, two pictus catfish and three small mono sebaes. My tank has a large power head filter that creates quite a strong current (1500 litres a hour) I've also added extra compartments on it with extra filter material, as well as two sponge filters. Would a group of angels about 5 or 6? Be alright with a bit a current?
