Okay, so to start off I don't own this fish, my friend does. She has 3 in a 10 gallon tank and I'm extremely worried about them. For all 3 shes gonna need an entire pond and her Catfish are gonna probably pass away if she doesn't buy a bigger one. I told her to give them to another shop or owner so they don't get neglected and she said that she will upgrade the size. I know for a fact she has no idea what she's doing with her fish. Please help.
