I bought two redtail catfish online (I do not have a LFS near me that has big fish) and they came today. They are little, so will be in my growout tank until they can hold their own in my pond. I have noticed an issue though. One of the catfish is missing a pectoral fin. It isn't torn, it just isn't there. He is about 5 inches, so I assume he is doing well without it, but will this be a problem later? Should I call the people I got him from and return him? If it was just going to be him in the pond and he was doing well, I wouldn't worry, but there will be competition for the food. I do not want to have a bad situation develope once I move him. What do you all think?
