Received the False Julii Cory juveniles in good condition. The three bands are clearly visible and they seem active and healthy. Easy to care for and fits well in my 10-gallon community tank with tetras and rasboras.

The fish arrived promptly and look vibrant. They have settled into the tank well and are active at the bottom. A good choice for beginners looking for a hardy, peaceful catfish.

Great addition to my aquarium. The coloration is distinct and they don’t stress other fish. I’ve kept them for three months now and they’re thriving.
