The Similis Corys are very active and stay calm in my planted tank. I’ve kept them with neon tetras and they don’t compete for space. They dig in the sand and seem to enjoy the environment. Easy to care for and a great addition to a community setup.

They’ve been in my tank for three months and are still healthy and active. I appreciate their peaceful nature and how they don’t bother other fish. Feeding them a few times a day keeps them happy and alert.

Great choice for a planted aquarium. The fish are colorful, stay active, and don’t stress other species. I bought a group of six and they all seem to get along well. The substrate is fine and they forage naturally.
