Tropisternus Water Scavenger Beetle

Description

The Tropisternus water scavenger beetle is a small genus of beetles measuring about 1/4 of an inch. They are a fun addition to any tank of aquatic beetles. They will scavenge on fish food pellets (sold separately in the links below) and a variety of other detritus in the tank. We keep them with diving beetles and don’t see predation on them by the diving beetles.

$4 each. Choose overnight shipping only through Sept.

These active beetles tend to be rounder than the flatter diving beetles and they move their legs differently. The definitely spice up any tank with respect to diversity and are one of my favorites to watch move around because they swim differently than other beetles in the tank. They are sort of medium in size as available aquatic beetles go and in certain light, these otherwise black beetles reflect a greenish or metallic gleam.
