I have had 2 male sword tails and 1 female sword tail everybody gets along great until about a week ago. My orange male sword tail and the orange female always stayed together, now I may be wrong but she looks pregnant her belly got a little bigger since this the male pineapple sword tail keeps the other male sword tail away from my female, now to the point where the orange sword tail hid behind a plant and won't come out, and the pineapple sword tail keeps following her and won't leave her alone. I'm afraid my orange sword tail will die. I don't know what to do I feel terrible that her mate had to go hiding to be left alone and away from the pineapple sword tail, he just chases her around the 10 gal tank and won't stop. I can't believe how much energy he has. Anyone have any suggestions, please!!
