I bought a white lionhead yesterday. It's a beautiful fish but this morning, I noticed that the caudal fin is not equal. The left side is normal but the right side is slightly bent? deformed? i don't know, it's just different from the other side. The fish is just 2 inches long. Is this fine?is that going to straighten by itself?

Unfortunately any folds,bends or kinks cannot straighten over time.Unequal size of tail cannot assume equal length as well.You got to be prudent in selecting your purchase in the future.
