Earlier today my dwarf gourami was struggling to swim lying at the bottom of the aquarium. I put him into a tipper ware container and he is lying there. When I walk up he will swim and get oxygen etc. I put peas in the container I case it was a bladder issue but he doesn't want to eat. I think his tail fin is ripped and is the cause. I want to know if he is ok and if he can get oxygen. Should I put him back into his 20g home that is heated. Room temp is about 70 degrees.
