Pygmy Yellowtail Angelfish in the ideal aquarium

Pygmy Yellowtail Angelfish - Centropyge flavicauda

Setting up the best aquarium for the Pygmy Yellowtail Angelfish species will require a well filtered minimum of 55 gallon/208 liters tank that is within the required parameters of a saltwater habitat.

The tank should be decorated with lots of live rock to provide them with hiding places and should also facilitate the growth of microalgae upon which they would graze.

These species are not suitable for a reef tank as they would often nip at the precious corals, sessile invertebrates and the clam mantles.

They should be the only dwarf Angelfish in the tank. They tend to be very territorial and will often harass any docile fish and may even kill other dwarf Angelfish species.

They are suitably kept in a harem of one male with several females. They would naturally breed in the tank.

Pygmy Yellowtail Angelfish feeding

Pygmy Yellowtail Angelfish are omnivores and their food should be based on a variety of meaty and vegetable matters. Spirulina, fresh or frozen mysis shrimp, other high quality prepared foods and a lot of marine algae.

Pygmy Yellowtail Angelfish breeding

Just as with most Angelfish species, there is no visible difference between the male and female individuals. However, there have been several success records of breeding them in captivity.
