My brother has a 4.5" female motoro. He said he came home and tested his water and the ammonia was in the caution area? WHat ever that is. anyway he said his motoro is breathing hard and is a whitish color and floating on the top. Sounds like maybe ammonia burn or just stressing from ammonia. What would be a good thing to do to try to save him? I told him a big water change, and adding salt. Is this the best move? he also has another 100gallon setup that has been cycled better. I told him the stress of moving her may kill it.
