I have a 30g biocube with a mandaren dragonet, 2 clownfish, and a purple fire fish and red fire fish. I have had the clownfish and dragonet for little over a year and decided to add the fire fish just 2 weeks ago. I am beginning to notice rips on the red fire fish fins and the purple firefish showing dominince and overpowering the red firefish. I feel bad because the poor red one isen't eating and I dont know what to do ;( help?

Unless you remove the Red he/she is going to die or jump out of the tank.
