Ultra-rare - and very cute - 'Pocket shark' discovered

Researchers have discovered what is possibly only the second specimen ever found of the small and very rare ‘Pocket shark’.

While the Pocket shark (Mollisquama sp.) might be small, the common name actually comes from the distinctive orifice behind its pectoral fin — one of many physiological features scientists hope to better understand.

Aquarium Snails: What to Keep and What to Avoid

While some snails can do damage in your aquarium, others are lovely to keep.

At one point or another, every aquarist has experienced an unexpected outbreak of snails in the home aquarium. It can be incredibly frightening, too. There are these small little animals in tremendous numbers that have seemingly appeared overnight, and you did not put them in the aquarium. Where did they come from?

Bicolor Angelfish

p-66076-Bicolor Angelfish

Thought by many to be the most striking of the Centropyge group of dwarf or pygmy angelfish, the Bicolor Angelfish, also known as the Two-colored Angelfish or Oriole Angelfish, is a vibrant yellow on the anterior half of its body and a deep blue on the posterior half. A splash of deep blue extends upward vertically from the eye to the top of the head and the tail is yellow.

A minimum of a 70 gallon tank with lots of hiding places and live rock for grazing will offer an environment in which to thrive. Not a good reef dweller, the Bicolor Angelfish is prone to nip at stony and soft corals (sessile invertebrates) and clam mantles.

It is hermaphroditic, very difficult to breed in an aquarium, and has no distinguishable differences in color between male to female. The Bicolor Angelfish requires a diet ofSpirulina, marine algae, high-quality angelfish preparations, and mysis or frozen shrimp.

Flameback Angelfish

p-66297-Flameback-African

The Flameback Angelfish, also known as the African Pygmy Angelfish or Orangeback Angelfish, has striking contrasts of blue and orange-yellow colors. While the body is predominately blue, there is a broad and bright orange to yellow swatch from the head along the back to the tip of the dorsal fin. The caudal fin is yellow and somewhat transparent, which distinguishes it from the Brazilian Flameback Angelfish (also known as the Fireball Angelfish – Centropyge aurantonotus).

The Flameback Angelfish requires a minimum of a 55 gallon tank with lots of hiding places and live rock for grazing. On occasion, this fish may nip at SPS and some species of polyp corals in the reef aquarium.

The diet of the Flameback Angelfish should includeSpirulina, marine algae, high-quality angelfish preparations, mysis or frozen shrimp, and other meaty foods.
