I currently have 2 clowns, yellow tang, fire fish and neon goby and is wondering whether I should add a couple more yellow tail damsels. I am a bit reluctant to add them because of their aggressiveness. My clowns are always chasing off the fire fish and goby. And it looks like they might be victims of the damsels. Does anyone recomend keeping damsels with fire fish or goby and whether they will live happily together?
