I have a 10g freshwater tank w/ 3 Mollies, 2 Mystery Snails, 4 plants & 2 Neons.
My female Neon, I call her Kitty, is pregnant. I have a Molly that's already in protective custody & I have no space to sequester her so she's in general population. I have plenty of hiding spaces but these guys seem to only want to be out in the open. Her belly is full & distended & when I watch her belly, it changes shape. It's one big knot then it moves around & becomes 2 then it fuses back together. Not like in a continuous cycle but constant. Sometimes it divvies up into 3s. It looks like an Alien that keeps missing it's cue.
I don't know what to make of it. She floats, swims, eats, breathes, gets along just fine except for this. Do you have experience w/ this sort of thing?
