Convicts, pictus catfish, firemouths, Raphael catfish, red tailed black shark, synodontis catfish maybe
My female Dempsey is crazy mellow and lives with an angelfish but I wouldn't recommend it, just depends on personality, just add the meanest fish last and know that males can be more aggressive
Yes, I agree with Buba2424. I don't recommend Angelfish as it's a very risky situation but you may have a chance if you let them grow up together and get to know each other before they get to their mature adult sizes. Females would probably be the best candidate for that to be honest. Best of luck!
