Potter Angelfish is somewhat interesting to have however depending on your " how well " established tank is, fish mates, and reef system? dead coral system? Potter is known to be difficult to keep in tank with dead coral oraments. Unless you have a reef system, big tank, very well established tank, and WATER QUALITY. You should have no problem keeping that one. But.........For how long?
Hope this helps and good luck.
That was 20 years ago since I had that one and It lasted about a month... No luck....
