Hi all, I have a dwarf gourami which has stopped eating for two days. There is a slight bulge to its stomach and has white stringy poo, so I'm thinking either constipation or internal parasites? It has lost colour as well but still swimming fine. Maybe some pineconing but not sure about that hoping it not dropsy which I been reading about. What is my best course of action? What do I try first, do I quarantine it? I have in the tank neons, danios and another dwarf gourami, they are all fine. I clean the tank weekly with about a 40% water change and gravel clean once a fortnight, none of my water parameters have changed. I live a long way from town so any home remedies would be appreciated. Thanks in advance.
