This Lamarck is getting cleaned of parasites by the cleaner wrasse in the photo. The Lamarck is not a spectacular beauty but it is an interesting fish and is hardy for an angelfish. They are somewhat shy so provide them with plenty of caves and hiding places.
Maintenance difficulty:
This fish is fairly easy to keep. About the same as most angels it seems to do well if given enough variety in its diet.
Maintenance:
It is important that you feed angelfish all kinds of live, frozen, and prepared formula foods. Best to feed small amounts several times a day. A good formula that can be made at home consists of mussels, shrimp, squid, and spinach.
Habitat: Natural geographic location:
This is something of a rare fish ranging from the Solomon Islands and New Hebrides northward to Japan.
Natural Foods:
Eats plankton in midwaters.
Social Behaviors:
Found in medium to large groups that feed in waters well above the bottom.
Sexual differences:
One of the few angelfish that display sexual dimorphism. The male has a yellow spot on its forehead and longer more pointed caudal fin. The male and female have often been described as different species because of these differences.
