Hatchetfish
Also known as the Swallow Fish, Chest-Knife Fish, or Sternoptyx, the hatchetfish is a group of unusually shaped small freshwater fishes. Its body is extremely laterally compressed with a greatly protruding belly, giving it the silhouette of an ancient stone axe—hence the name.
Whitefin Surgeonfish
The whitefin surgeonfish (Acanthurus albipectoralis) is a Great Barrier Reef tang that grows to ~33 cm and is uniformly black with a white rear-half pectoral fin. A marine (saltwater) species, it is aggressive to its own kind but peaceful with others, and needs a large reef tank with stable, high-quality water and both meaty and algal foods.
Central American Snapping Turtle
The rarest of the four chelydran snapping-turtle subspecies - large, dark, pugnacious, and really a 'meat turtle', not a home pet.
Spotted Turtle
A tiny, starry-spotted North American gem - one of the smallest turtles, beautiful, and of real conservation concern (pricey and declining).
Egg Turtles (Mud & Musk Turtles)
A collective name for the small, egg-shaped turtles of the family Kinosternidae - the mud turtles and musk turtles - popular for their compact size and personable behaviour.
Burmese Black Turtle
The Burmese Black Turtle (Melanochelys trijuga indopeninsularis) is one of the seven subspecies of the Indian black turtle (three-keeled turtle). Common in Chinese pet markets — almost all sourced from wild capture — it is inexpensive but plain-looking, so it is kept in modest numbers.
Mississippi Map Turtle
The Mississippi Map Turtle (Graptemys kohnii) is the most common and cheapest map turtle. Juveniles resemble red-eared sliders and are often sold alongside them, making it a popular beginner water turtle.
Herrera’s Mud Turtle
Herrera's mud turtle (Kinosternon herrerai) is one of the fiercer mud turtles — looking like a tiger-striped razorback but with the pugnacious personality of a narrow-bridged musk turtle. A rewarding but pricey and aggressive captive that is best kept alone.
Altum Angelfish (Pterophyllum altum)
The altum angelfish (Pterophyllum altum) is found in the Orinoco basin of Venezuela and Colombia. Not very hard to keep, but it needs oxygen-rich, roomy water and must not be frightened. Because it is hard to tame, artificial breeding is difficult and it should not be mixed with small fish.
Yamabuki Ogon
The Yamabuki Ogon is an all-golden koi bred in Japan, prized by koi keepers as a wealth-bringing fish. Peaceful and not territorial, it likes slightly alkaline water (pH 7.2–7.5) and lives 6–10 years on an omnivorous diet, with feeding portioned to about the size of its head.
