Hello everyone. I am new to this site so pls bear w/ me. I had purchased a mickey platty 1 week ago and its always lying behind a plant. Its too thin to be pregnant. Its acting very weird compared to the other fishes i have (behaviorwise). And now, the other platy i have (female) is also just sitting next to her behind the plant. Do you think theyre sick? Something must be wrong w/ them. But they do eat and they swim around sometimes. My next question is, do fish ever sleep?
