good to hear coralline's coming around. Unless u don't plan to add more fish, the tangs should've been added last bc once they are established tangs dont take kindly to new comers. Also just an FYI in case u were not aware - the powder blue and scopus may not do well long term in a 93 cube since they'll outgrow the tank. The powder blue is one of the most aggressive tang's and may become hostile in a 93 esp w 2 other tangs. Unfortunately it is also one of the more sensitive tangs that is notorious for getting ich, for which stress often triggers it. Someone once told me "if u just look at it wrong, it'll get ich"...
Yeah, the fish were quarantined before I put them in the tank. Especially with copper. Somehow the flukes got past the quarantine. But I specifically chose the powder blue and Scopus because they don't get as big as most other tangs. Something like 9 inches. But to be honest the powder blue is the most docile one, very calm fish. It's the Scopus which is the crazy one sometimes. They actually all swim around together and sleep together. I will be adding other fish. And will be taking appropriate steps to ensure a smooth transition for any other fish i put in the tank. After all a humans ability to out wit and manipulate nature are what make us the dominant species on earth. But I really won't be adding that many more fish.
