Anyone that can advise me? I fed a blue crab lastnight. It was messier than usual. I got up this morning to do a water change. I tested this tank along with my 120. I have .50 ammonia. I am performing enormous water change but I have the 120 (anyone familiar with my 120 set up?) should I transfer her now. I am worried that I won't be able to get the amonia down fast enough. She is looking very good, changing colors, eyes not dialated and active, no heavy breathing. Should I keep her in the 50 or transfer her. Sorry I am rambling but I am scared and in panic mode.
