I currently have a red tail catfish that is 3-4 inches and is in a 10 gallon by itself. I have a 750 gallon pond outside my house ( alot of ppl ask me abt the temp.and stuff, i live in india where the temperature is perfect and the prices of fish are really really cheap lol ) which i will move it into in a bit. I feed him live minnows. He rarely moves and is never very social and he has a brownish tail currently. How do I make him feel more comfortable and how do I make his red tail appear faster. I had to take him out of the 750 gallon because it wasnt didnt get any food down there and because i was scared my paroon sharks would hurt him. Please give me tips on how to get him very social and healthy.
