:-[ My 5 cb's ( had them 5 days, new set up as I have already posted) All has been well, lively swimmers until 8 hours ago. They stayed close to the bottom and hid in a group behind filter pump. They have been out for feeding time and have been out more since the lamp was switched off. Water had VERY slight ph raise but all else ok, even took sample to lfs to double check. Have done water change as advised but I am worried. I am aware that they can be shy etc. My dad saw them and asked me if they were laying! I have just looked in again, we believe that we have 2 male and 3 female. At the moment the girls and one male are in hiding, other male flitting about then hovering over the bottom wagging his tail very fast ,as low as possible in one place, then up and off to next spot! Do the sound normal, ill or just slightly nuts like the rest of my pets ( they are all quirky, I seem to attract oddballs!) HELP!!!
