Agression

[Ckarnuth]

I recently added a diamond goby to my tank and my Singapore Angel and Powderblue Tang seem to be really agressive towards it, to the point now that when the goby even sees the other fish he darts back to his burrow. Can anything be done? The Singapore angel has now started hanging out at the burrow entrance just waiting for the goby to come out.
This is a 66 gallon tank to allow the fish to get larger before being migrated into the 750 gallon with full grown specimens.

Thanks in advance

They are both larger agressive fish, the Diamond is a rather small, skittish fish. This is a bad combo to have in a smaller tank (for relative fish size) like that. Diamond might get eaten or stave.

In this case, the diamond is actually the largest of the fish on the tank. He is about 5" long, while the angel and tang are each only about 3".

Its still skittish and not nearly as fighting capable as the angel and tang
