Cichlids living with.....

i had to rescue my pleco from my cichlid tank, then i had to rescue one of my cichlids. now they are living together cautiously, the yellow with black on the dorsal fins hides a lot, sometimes annoys the pleco, and vice versa. they are in a 30+ tank, lots of hiding spots. the pleco used to have torn fins.
 
I have a blue phantom pleco in w/ a decent size severum w/ absolutely no probs.... and I have a clown pleco in w/ an angel and the little clown actually is the aggressor. lol It chases the angel away from the sinking pellets all the time.
