I have a 40 gallon breeder, currently have 2 clowns and a blue devil and yellow tail damsel. The problem is the damsels are aggressive to any new additions lately. I added a blenny and a cardinal and they stressed/bullied them to death. The clowns and damsels get along quite good, been in the tank for 5 months together. My choice is to rid the damsels but I kinda like the look of them and are almost impossible to get them out with a net. Are there any fish that i can add they will get along with the 2 clowns and 2 damsels?, i want to add at least two to four more fish but don't know which fish will be a big happy family together, any suggestions?
