Procatopus aberrans - Males

Details -

Overview:

I just found out from Jouke Vdz, an internationally respected fish expert, that this is actually Procatopus aberrans, not Procatopus similis. They are closely related and have the same behavior/care as similis. Thanks, Jouke, for clarifying what these are! - 1/11/2019

My favorite lampeye! These are gregarious, peaceful, and colorful fish. Their beauty is subtle, but not so subtle that saying it is "subtle" is just a nice way of saying that they lack color. These have plenty of color, but it is in a pastel pallet as opposed to gaudy, saturated tones.

Hardy and easy to feed, this fish eats anything it can fits in its mouth. Flakes, pellets, frozen foods, live foods, and Repashy are all consumed with gusto.

This lampeye killifish does best in a group where it can shoal around the aquarium with others of its kind. Like all lampeyes, the bigger the group the better!

An easy fish to keep and to breed. If you are new to lampeyes, these are a great choice.

Some of the prettiest fish on the planet are killifish. This diverse group is sometimes referred to as the "egg-laying tooth carps" in order to distinguish them from their close relatives, the livebearers. In many ways, a killifish is a livebearer that lays eggs. The non-annual species generally live as long as your typical livebearers. The annual species typically last 12-18 months. Like their livebearer relatives, most killies are easy to keep and feed. They are also famously hardy.

Setup Considerations:

Killifish are one of the most diverse groups of fish on the planet. They have adapted to many habitats from hypersaline environments to pristine rainforest streams to temporary pools. Therefore, there is no "one sized fits all" way to keep killifish. However, most killies in the aquarium hobby can be kept in anything from a small bare tank with a sponge filter and a spawning mop to a large planted show aquarium with a community of species with an appropriate size and temperament. The one thing almost every killifish setup needs is a tight fitting lid. Killies are expert jumpers. If there is a hole in the lid, they will find it and they will manage to jump out of it.

Diet:

Most killifish in the aquarium hobby are carnivores. A few of the pupfish species are herbivores, but besides the Florida Flagfish, pupfish are rarely available to the average aquarist. Die-hard killie keepers generally feed their fish lots of live and frozen foods. However, that is not strictly necessary. High quality dry foods such as flakes, pellets, crumbles, etc. are also good food for killies. A rotation which includes frozen and dry foods usually results in fat, sassy killifish.
