Hi, you seem to be very over stocked. I have 8 guppies in a 10g and i have to do 2 50% water changes a week. If not, my Nitrates will go out of control. How long is it set-up. Is it cycled. Are you testing your water regularly and doing PWC's???
Sorry for all the questions but if give people an idea off what might be causing the problem.... Ian
