Well... I had a little red slime algae outbreak and blacked out the tank for only 24 hours. I came home from work today and turned the lights on. the algae seemed to dissipate. Then I looked over at my BTA. Is this normal? This is the first time I have seen it closed up to the point to where it is almost inside out. I fed the tank and actually saw Mator take a piece of food to it but it did not seem to stick to its tentacles. He tried a couple of times before eating it himself. I then spot fed the BTA and managed to get a piece of mysis to the center by its mouth. Not sure if it ate it or not.
