Overview

The eyespot dwarf pike is a dwarf pike cichlid scaled for a normal tank. It lurks near the bottom among wood and leaf litter, ambushing small prey, and it is not a beginner's fish.

Did you know

The eyespot dwarf pike's new genus name honors Alfred Russel Wallace, who studied the fishes of the Rio Negro in the 1850s. He lost most of his specimens when his ship caught fire on the voyage home, and the science was later rebuilt from what survived.

Caring for the eyespot dwarf pike

Keep the eyespot dwarf pike as a single fish or a bonded pair rather than a group. A pair needs at least 42 gal (160 L), aquascaped with a sandy floor, a bed of leaf litter and tangles of driftwood. Stain the water with tannins from botanicals, and keep the light dim, with some shade.

Keep the water soft and acidic, at 75 to 82°F (24 to 28°C) and a pH of 4.8 to 6.5. Feed small meaty foods such as frozen bloodworm, mysis and chopped items. Wean it onto prepared foods over time.

The eyespot dwarf pike is an aggressive micropredator that will eat anything small enough to swallow, and it can be nippy. Choose peaceful tank mates too large to be eaten but not big enough to bully it. Keep them out of its litter-strewn corner.

Females carry the eyespot the name records, a dark ocellus ringed in red on the dorsal fin. It is a cave spawner that hides its eggs and guards the fry. Its need for soft, acidic water makes aquarium breeding hard.

Good to know

The eyespot dwarf pike is a pike cichlid in the family Cichlidae. A 2023 revision of the pike cichlids moved it into the new genus Wallaciia.

In the wild

Wallaciia notophthalmus lives in the blackwater shallows of the lower Rio Negro and middle Amazon. It threads through leaf litter and submerged wood in soft, acidic, tea-colored water.
