Hi,
It's been a while since I posted, however within the couple of months some of my guppies have begun to have clear(it sometimes has a whitish sheen under the light) poo, I have read many things on forums over the internet and it's difficult to tell what exactly are the differences between fish who have parasites or bacteria. The fish, as i've lost a couple, waste away, their stomachs end up flat rather than the round underside of the fish and then they die. The fish are fed flake food once or twice a day and frozen bloodworm/daphnia and algae wafers around once a week. The tank is 10 gallon, water is 23c : ammonia 0 nitrite 0 nitrates vary between 20-40, i've never been able to get them under 20, ph is 6.5. There are currently 3 adult females and one adult male and around 20-25 from (a week old to colouring up) I am in the UK I have used interpet anti internal bacteria, and waterlife sterazin, with no effect. The tank has around 20% of water changed a week. Any help would be appreciated
Thanks in advance
