I just purchaced a GouramI Dwarf yesterday. This morning I noticed that he is hanging out at the top of the tank, and looking very sluggish. He also looks like he has "webs" coming off him. His colors are still ok, but I don't want to leave him in there and have my other fish die. I don't have a quarantine tank, as this is my very first tank, and my first couple of weeks with it. I have checked the ph, Nitrate Nitrite and Ammonia and they seem to be normal....I only have test strips which the Petco gave me at the time of my tank purchase. Please help...I don't want to have to start my tank over. All the rest of the fish seem to be fine....4 neons, 1 platy, 3 guppies !!
