Help! My Aussie gold torch seems to be receding and dying. I bought it around Sunday and ever since then it is still relatively closed. Also, it recently fell of a rock into the sand. We are also battling Cyanobacteria in the tank currently. The nitrates are also practically at 0. Everything else seems to be doing fine but that one torch. How do we get the nitrates up without buying new fish? Also can we save this torch?? Please Help!
