General information regarding Passer Angelfish
The adult is mostly dark blue and has an elongated white vertical stripe that extends downwards from the dorsal fin approximately two-thirds of the way towards the pelvic fin. The dorsal fin is rimmed with yellow. The pectoral and caudal fins also have yellow fins, while the ventral fins appear yellow on females and white for males. The juvenile is orange, with only one white and several blue stripes. This Passer Angelfish can grow to more than a foot long therefore it needs a huge aquarium. It is a robust fish, however it can be aggressive, which is why it should be kept in a tank with tank mates who are semi-aggressive. It feeds on live rock and may be aggressive towards soft and stony corals (sessile invertebrates) as well as clam mantles which is why it’s not a suitable choice for an aquarium with a reef. A Small Juvenile aquarium will include the Juvenile colors, the Small-Medium color will be changing towards an adult in the midst, medium will have a subadult and the Large with Adult coloration.
