Black Marble Angelfish – Cuboid Nature Aquarium

Black Marble Angelfish

Black Marble Angelfish(Pterophyllum scalare) combines the swirling, irregular marble pattern with a predominantly dark base — the dark areas of the marble pattern are a deep, rich black rather than grey, while the lighter areas remain white or silver. The contrast between the deep black and pale patches creates a high-contrast, dramatic version of the classic marble pattern.

Feeding & Care Tip:Sera Vipan Tropical FlakesandHikari Micro Pelletsmake excellent daily staples — crush flakes for juveniles. Supplement 2–3× per week withHikari Frozen or Freeze-Dried BloodwormsorHikari Vibra Bitesto bring out best color and condition.Hikari Frozen or Freeze-Dried Brine Shrimpmake an excellent treat for adult fish. Feed 2–3 times daily in small amounts.

Angelfish are tall, laterally compressed fish that need aquarium height as much as length — a minimum of 18 inches of water depth is recommended, and 24 inches is ideal for adults. A planted aquarium with tall plants such as Amazon Swords, Vallisneria, or tall Cryptocorynes provides the cover and vertical structure this species naturally inhabits. Gentle filtration is important — strong currents stress angelfish. Keep with peaceful community fish of similar size; avoid known fin-nippers and do not keep with small fish such as neon tetras that may be eaten as adults.

Angelfish are devoted and fascinating parents. Pairs bond for life — presenting a flat, vertical surface such as a broad Amazon Sword leaf, a smooth slate tile, or a piece of PVC pipe triggers spawning. The female lays rows of adhesive eggs which both parents fan and guard obsessively, chasing away all other fish in the aquarium. Eggs hatch in 24–48 hours and the wriggling larvae are typically moved to a pit in the substrate by the parents. Fry become free-swimming after another 5–7 days and can be fed freshly hatched baby brine shrimp. Note that many generations of captive breeding have reduced parental instincts in some strains — if parents eat their eggs, the eggs can be removed and hatched artificially with an airstone.
