I know this is not the best picture but the BTA is off in a cave where i cant get a good light to him. He looks like a flat white. with some green to him. I have tried feeding him, I didnt see a reaction to the food. Like last week he was bubbled up going on 8 days now he this way. All of my water checks ok. There has not been any chance in temp. The tank has been running since June, and the ph also stays around the same lvl's.phosphate =0 test 2 days ago.
