I have 2 humbug damsels, one clownfish, 2 yellow tailed damsels and a dwarf blue angel (I think as I inherited them all and not sure about this guys Genus). I added in a Fire Goby two days ago. When I put him in the water I then fed them and he was right in there going after the food like the rest of them. Until the bigger of the humbug damsels started going after it. The little goby fought back for a bit trying to eat but then gave up and dove into the LR. I havent seen him since. Will, he come out? Will the Damsel let him or will he just harrass him to death? Is there anyway I can make the Damsel not so territorial? If not, does this mean I can never add more fish?
