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??

 

sounds nasty whatever it is - maybe a uv sterilizer would help?? but then again i think they kill micro-organisms.
Perhaps a massive water change to get the critters out?

I really dont know??

Im intrigued to find out what it is thats in your tank

 

I took out the rest of the fish that were in there for now and Im breaking the whole tank down Im not taking any chances because those white things are everywhere and what they did to my fish is grusome

 

Isopods? i think they eat fish and are somewhat small.......

 

yes they are

 

Click on the link - there is a section on isopods and pics on what they look like
if it is then you'll know

Welcome to Saltcorner.

 

breaking own tank was a good idea. i would treat fish with copper to kill existing parasitic isopods. then nuke LR and Everything in tank with 50/50 bleach and start over :-/ wait till that Tangster or someone else confirms what i believe to be the only answer..........

 

Actually I got a leather from a women a few weeks ago (I got rid of it though) and she said her tank was full of pods (but she never mentioned them eating her fish, but she had a lot more algee and stuff in her tank.

 

yea I was thinking that would be best I have to get some copper because that paragaurd stuff did not do the trick

 

well if its a tank you keep or will keep coral in then maybe you could try osmotic shock instead?
