i have a yellow tang, small blue damsel, small 6 line, small diamond goby, dragon goby, cleaner shrimp, peppermint shrimp, fire shrimp, lots of hermits, lightfoot sally and emerald crabs. everyone seems to get along well. the firefish was only 1 week in the tank so he was pretty new, but nobody chased it. The other two fish i lost awhile back was probably from the ich outbreak and the medication probably stressed it. I will never medicate my tank again like that. it did way more damage than good. i probably would of had a better survival % without medicating the tank but just feeding heavy garlic and more frequent but small water changes.
