 HELP!! Something is eating my fish alive!!
Ive had these little white things floating around my tank the last couple weeks (millions of them) they just look like little spots its like there is white dust all over the whole tank so much that is looks cloudy, and also Ive seen some little worms in there I didnt know what they were or if they were good or bad so I have been treating the tank with paragaurd in case they were bad. but they just continued to multiple. a few days ago my butterfly died and I couldnt figure out why first its eyes got glazed over then it was dead. then last night my puffer was covered with the white specks and then it died. and then this morning all 3 of my clowns were dead. and when I pulled them out they were covered in the white dots that were moving all over it and eating it all their fins were devoured!! I dont know what it is or what to do!! I took the rest of my fish out dipped them in clean salt water then added them to my nano cube which has just been sitting cycling the last couple weeks, but I dont know if the white things will continue to be on the fish and then contaminate the nano or not?? I am taking down my whole 90gal and killing all the like rock and I am going to throw out the gravel I think and replace it with new stuff. will this be enough or is there anything else I can do?? What can I do to keep the rest of my fish who where in the contaminated tank alive??
