i just got my second senny and he has already made three little droppings in his tank in a couple of days (he's by himself so im sure its him) my other senegal, which i have had for a few months now, doesnt seem to poop at all, ever. he's healthy and all, eats well, plays well, lives well, but just doesnt ever seem to leave his business all over the place, or anywhere for that matter. do i just have a very clean senegal or is the other one just very messy, or somewhere in between? thats kinda annoying having all those black things all over my nice white sand. i might have to switch to black sand when i upgrade tanks.
