she's been extremely aggressive today and yesterday, and doing a lot of digging. Also her papilla (genitals) are very swollen so have been watching her for the last 3 hours or so...sad i know but very interesting for me as i have not bred fish for a few years now. After watching her fail to get the sand completely off the bottom i decided to put in a flat rock which she was obsessively cleaning for about an hour. and now she's been laying for about half an hour, and ther are thousands.
