I rearranged the tank

[Delphinus]

Looks great.

I was really worried about my tang towards my CBB at first. For the first week or so I was convinced I would have to catch the CBB for his safety. However like yours he was small and could escape into the rockwork where my sailfin tang could not as easily follow.

It took a few weeks but they did eventually learn to tolerate one another. Anyhow, with luck, maybe this will be your outcome too. Good luck!

PS. The purple of that one coral is insane. It's practically all I can see.
