thanks for your replies
1# last water change was 25% last sunday (on a juwel lido 120l), was planning another today ( i use RO water from local fs) no other fish have been added, the father had no signs of illness or damage but i did notice in the days leading to his death that he would leave the mother and fry for extended periods and go and hide behind the plants in the back of the tank. no meds or treatments have been used. in the tank i have platys, corys, tetras, danios, and two angels, just a basic community. i have been spending this week setting up a cichlid tank for my kribs so i do have a place for them do you think i should move the mother and the fry now??? on last count i think ive lost about five since the father died so it seems the mother is struggling?? suggestions please?? thanks, sean
