Been doing fish for a long time now (meaning I have a bit of experience)
My question is I have this thing, looks like a small white potato growing in
my tank, it's about .5 inches across and sits in the same place all the
time. I haven't messed with it at all, just watching it grow.
It started smaller and in about 3 weeks has doubled it's size
No roots or filaments I can see, but they can be in the gravel bed
So any ideas,
I only feed fish food, flakes and some bottom feeder discs
