Angelfish
Cream Angelfish
Apolemichthys xanthurus

The Cream Angelfish demands high water quality since dwarf angels don't tolerate nitrates well. A 50 gallon or larger tank with lots of hiding places and live rock for grazing are recommended. Not a good reef dweller, the Cream Angelfish is prone to nip at stony and soft corals (sessile invertebrates) including clam mantles. It will also feed on filamentous algae and diatoms on the tank surface.
It is important that Angelfish are offered both vegetable and protein matter in their diets; feed every other day high-quality angelfish preparations, spirulina, marine algae, mysid or frozen shrimp, and other quality meaty foods. The Cream Angelfish is hermaphroditic (all males result from female sex change), very difficult to breed in an aquarium. keep only one per Tank.

Angelfish Care:
They should not be exposed to the physical stresses of a newly established marine tank. The aquarium should be set up and running for three or four months before adding any species of angelfish. This ensures that the nitrogen cycle in the tank has been completed and the levels of ammonia and nitrite are so low as to be immeasurable.
Acclimating Angelfish is very important, as these fish have been known to go into shock.

Because the members of this group are small, they are often housed in small aquariums, which is the worst thing you could possibly do if you plan on keeping passive fish (e.g., seahorses, pipefishes, batfishes, leopard wrasses, flasher wrasses, highfin shrimp gobies, fire gobies, dart gobies) in the same tank.
Sea Anemone: The long tentacles are equipped with stinging cells that paralyze prey. Anemones required excellent water conditions, moderate to strong current and intense lighting. A minimum light intensity of 10,000 lux is indispensable for them to survive and grow.
Coral Reef: Although corals are often mistaken for rocks or plants, they are actually composed of tiny, fragile animals called polyps. A polyp is a spineless animal. Polyps can be the size of a pinhead while others are larger, sometimes a foot in diameter. One coral branch is covered by thousands of these animals.
