We have a sick gourami and don't no what wrong with it, it's has a very swollen belly and drops to the bottom of the tank like its swallowed a rock, any ideas what's wrong with it??
It most likely has swim bladder disorder or dropsy. Do its scales stick out like a pinecone? Try to feed it some peas and nothing else. It might be constipated, so it's best to only feed it foods that act as a laxative.
