No visual symptoms at all. His scales not raised, he is not darting, not bloated, no symptoms at all? How long he is like that? Anything new in his tank at all? Why spring water ? Is your tap water has ammonia in it? Did you try full water changes daily? Its just if there is not other symptoms but being lethargic may be something in the water?
Well you talking to very knowledgeable people here so you guys covered all questions.
Well he's... I'm not entirely sure. Something is going on with him but we're not exactly sure what. I've been talking with lilnaugrim, Sakura8 and LittleBlueFishlets so hopefully between us all we can figure it out. What do you think? It's a really, really long story but basically he's lethargic. His heat is fine and I can't see any other symptoms. He seems to perk up a bit after a fresh change of spring water, but after several days goes back to being lethargic.
