Hi guys, I have 1 male and 3 female platys in a 10 gallon tank. Recently I've noticed that the females like to just sit on the bottom of the tank and they look like they are asleep or something. They just sit/lay there not moving. I f I tap on the glass lightly they will "wake up" and swim around a bit. Anyways, I was wondering if anyone else has noticed odd behavior like this, could they be in the later stages of pregnancy or something? It just seems very odd because they don't move at all, they just sit on the bottom. Thx for any help you can give.
