I have a pair of Percula's and one is about an inch long and the other is about 2 1/2 inches long. They are twitching like normal but the bigger one's stomach is bulging out . I asked my LFS and they said that it isn't a sickness or disease. They said it could possibly be pregnacy but the little one is small and I dont kno if it can reproduce this young. What do you think. Do you think is is pregnant?
