Madagascar Killifish

Pachypanchax omalonotus is a non-annual killifish found in rivers and streams of Madagascar. It is considerably rarer in the hobby than Playfair's Panchax and is notable for its rows of red-orange spots on a greenish silver body. As a species under pressure in the wild from habitat destruction, captive propagation by dedicated keepers is especially valuable. Its larger size and assertive temperament mean it needs careful management.

Feeding: Live and frozen invertebrates; insects, Artemia, Daphnia; dried food accepted. Behaviour: Males territorial and may be aggressive to females; keep trio with hiding spots. Compatibility: Species tank only; predatory toward small fish.
