Neptune is laying on the bottom of the tank. At first he was laying on his side and swimming (like rubbing), then I cleaned his tank, and now he is laying on the bottom just sitting there. He has a redish pink spot on his side. I can not get it to show up on camera, it is not very dark but it spreads out over his whole side, he is cellophane. I made a mistake, and went two weeks between water changes. The water was fairly bad by the time I realized it was bad. It did not smell and was not murky, until I started cleaning it. Then it smelled of rotten eggs. The tank has two snails that were recently added without quarantine. They came from PetSmart, and I work there, so I trusted that they were healthy.
He seemed fine yesterday, and he seemed fine for a while again after the water change, and when I moved him to change the water. I did a 90% change. He did eat after I moved him back into the tank following the water change.
Any recommendations? I will fill out the "please fill this information out" now.
