Sorry I have to keep quoting or it won't let me reply lol
They are black balloon mollies. The largest one seems to have a white spot, can't see it too well on the picture. I only brought them a week ago so can't really tell if they are acting differently. From when I put them in the tank until moving to the breeding box, they didn't move from the corner, which is where the heater is.
