They are around but at full size you are probably paying a premium price. I tend to buy fish online more now than in person just because I'm in a smaller city with a bad selection. My buddy has a 500 gallon Discus tank and bought 200 cardinals off Aquabid and 90% were DOA. The guy gave him credit and he ordered another 200. This time they came in 90% alive but looked like crap. Skinny as hell. Half died the first day and the rest of the batch over the next couple days besides about 20 he was able to salvage. Fought with the guy for a week before he got his money back. He's on Long Island. Told him a couple places to check out. Ill leave names out for now but the one had almost fully grown fat ones for $13 apiece. Crazy. He sent me a pic. Ill post it when I find it. But I wouldn't but any fish that delicate or expensive if there was a chance a fish in my tank could eat them. What kind of catfish are we talking about?
