Good question. I picked it up on the smaller side, maybe 2" in size, and not really remembering what the recommended aquarium size is. I typically use that has a guide and bounce between what live aquaria has and wet web media with Fenner. Anyway the 40 breeder has a good foot print with regards to depth and width - at least in my opinion - so I figured a pygmy angel of some sort was going in and it was a coral beauty or a flame back. Anyway - believe it or not a pet club by me has an amazing fish section with people who actually care and handling equipment to back it up. I saw the beauty there and picked it up and took it home.How would you say your coral beauties behavior has been in the 40??
My 40 breeder had left over rock from previous tanks established since 2001 so pretty healthy algae, sponges, and stuff that makes it look real. Four rather large hammer corals each expanding over 12" that crowded one side of the tank, and about 5 or 6 rose bubble tip anemones mixed in with button polyps and a few zoas and leather coral. It was able to roam around the corals an anemones without getting hurt while other fish not paying attention. About the only damage I could say it did was one of the hammers started to not open as much because that was its home oddly enough. It really liked zipping in and out of the branches and every day that is where I would see it wake up from in the morning.
I guess what I'm saying is I thought the tank had a good foot print for it to actively swim and I didn't have wall to wall rock. I did have too much with regards to hammers and anemones but that is why I was building the 210. So I never saw any signs of duress or aggression with anything. He or she has a pretty well rounded belly and nothing outside what I said of his/her home was left alone. Hope this helps - I find it a really pretty fish with a reasonable attitude.
