Recently I decided to buy a male convict. I had a female already and decided I wanted to try to breed them so my angelfish (in another tank) could have some tasty snacks. I put them both in the same tank (20t) and immediately the female began harassing the male. They're both about the same size, but she chased him all over the tank and harassed him to no end. I was afraid she was going to kill him. The next day it was vice-versa. Now, two days later, she's showing frayed fins and is very skittish. I've tried re-arranging the decor in the tank and even set it up so he can't see from one side of the tank to the other to see her. She's got lots of caves to hide in, but prefers to hide near the top behind the power filter. Any ideas how I can get them to breed without killing each other first?
