I spoke to soon. I began lowering the heat yesterday afternoon.....don't ya know this morning he is back to darting and acting nutty. He was floating kind of sideways...not completely but a bit. Diving, darting, just not normal. So, I disolved some salt this morning and did a 20% water change as well. Also, but the lil heater back in the tank. Let's see what this afternoon holds.
I won't say the rest of the guys are great for fear of jinxing myself.
