These are one of my favorite catfish. I had one for years. I bought him when he as 2" I didn't noticed until he got bigger, but he had no eyes. He was still a cool cat though. I kept him in a tank by himself to ensure he got food, but sometimes I wonder if I really needed to separate him. He seemed to find food without too much difficulties. Unfortunately, he died while I was away on my internship. My Dad said he put him in a rubbermaid to fix his tank cuz it sprung a leak and 2 days later, it died.
