I’ve had my Corydoras Simulatus for three months now. They’re very active and enjoy the algae on the glass. The fish are calm and don’t stress other tank mates. I added driftwood and rocks, and they love to hide in the crevices. Easy to care for and a great addition to a community tank.

The fish arrived healthy and look exactly as described. They’ve been in my 20-gallon tank for two months and are active during the day. I feed them a mix of algae wafers and bloodworms every other day. They seem to be adjusting well.
