The Lamarck?s Angelfish is hardy as well as interesting fish. It exhibits sexual dimorphism, where the males have a bright yellow blotch on the forehead in addition to longer and "sharper" caudal fin edges. Since the Lamarck?s Angelfish features opercular spines, which are used for defense, can lead to severe gill damage if it tangles in net. Therefore, a container with flattened net should be used to cover the top of the container reducing the risk of escape and injury. The juvenile Lamarck?s Angelfish shows very dark body with electric blue markings, but as it matures it will lighten and begin to change its color. Although, it is relatively peaceful with other tank mates, but when it is acclimatized in the tank it becomes territorial. But its aggression can be reduce if are provided with ample swimming space and shelter. The Lamarck?s Angelfish prefers to live in groups of single male and 2-6 females, or a small group of single male and two females in an aquarium of 240+ gallons. The tank should be well-established with live sand substrates and plenty of live rocks for grazing, refuge and territory. Since the Lamarck?s Angelfish is very sensitive to fluctuations in water chemistry, you should use the high quality biological and mechanical filtration along with the high quality protein skimmer.
(A) Alert - This fish cannot be kept with other Angelfish. If you're attempting to purchase two or more Angelfish for the same aquarium it will cause them to fight and most likely one will not survive, so if you're placing an order that has 2 or more Angelfish in it we will have to place the order on hold until we're able to contact you to ensure you're not putting them into the same tank. If you understand they cannot be kept together, but would like to purchase two or more in the same order(separate tanks, group order, etc.) you will need to write in the Special Instructions area at the end of the shopping cart that you understand they cannot be kept together. Tremendous time and effort is put into ensuring the health of these fish and it is very important that you're fully aware two Angelfish should not be kept in the same tank.They have the distinction among angelfish of being sexually dimorphic. Both male and female are a silvery-gray with horizontal black stripes from eye to caudal fin. The female's stripes are bolder with one extending into and covering the length of the caudal fin. In both, the long dorsal fin is black, although larger in the female, and the caudal fin is freckled with black.It is important to provide them with plenty of swimming room. Like all Genicanthis, they tend to be passive toward most other fishes.The Angelfish family is a group of colorful and elegant fish that are adored by boththe serious and casual observer. These fish are mainly available to the hobbyistunder the Genus Pomacanthus and Centropyge. Pomacanthus Angels are the larger morerobust species. The Centropyge Genus are made up of smaller fish that feed primarilyon algae from the reef surface. The adult Pomacanthus Angels usually have longdorsal and anal fins and a rounded face. The Pomacanthus Angels will change colorquite dramatically from their juvenile stage to adult stage. The Centropyge Angelsare found predominantly in the Indo-Pacific while only a couple of species, like thePygmy and Flameback Angels, are found in the Atlantic and Caribbean. At the sametime, the Pomacanthus Angels dominate the Atlantic and Caribbean while in theIndo-Pacific they are less prominent. The Centropyge Angels do not change colordramatically from their juvenile stage to adult stage. These smaller Angels areoften seen milling around reefs which they use for both shelter and as a foodsource. Angelfish are differentiated from Butterflyfish by the small spine thatextends from the bottom of their rear gill cover.
