Help me! I don't know what to do! My tank is a five foot 187 gallon tank. I have a school of five yellow tailed blue damsels, 3 smithi damsels, a bicolor angelfish, a royal gramma, a PJ cardinal, and a pair of true percula clownfish. Yesterday I came home to find the biggest 2 yellowtailed blue damsels laying a batch of eggs behind one of the rocks. I just went downstairs and I found the biggest yellowtailed blue (the one that was guarding the eggs) all chewed up, fins frayed, and bloody patches of missing scales! I netted him and put him in a quarantine tank, but the clowns were attacking him as he was trying to hide and now they have a clutch of eggs behind the rock were the damsel eggs were. The clowns are being alot more aggressive than they usually are, keeping all the other fish on the left half of the tank. What should I do? Should I just let the clowns keep going at it? I'd really rather not move them. Help Me!
 
Remove one of your clowns. Once clowns start breeding, they wont stop. Expect this sort of aggression every several weeks when they decide to pump out some babies.

The other solution is to buy a 40g B and let them be at peace in there and spawn.
 
the damsel didn't make the night. I am not going to take the clowns out, but I am going to give them an anemone once I upgrade the lights (around November). They have spawned before (in that same spot), but were never nearly this aggressive. I think it was because the damsels laid eggs in their spot. Hopefully the anemone will help with the aggression problem. If not, they will get their own little tank.
 
Anemone will make it worse...now they have something more valuable to defend, and a more definite territory. My opinion.
