I do add water conditioner to the water and clean the tank every week (he's quite messy)
He's still bloated and "coughing".
He doesn't have any skin problems, abnormal behavior, and he doesn't eat a lot in the first place.
But I was wondering, should I place him by my window where heat and light can come in? ( I'm not going to have the window open for long periods of time)
Or should i get a light or not do anything about it?
