Please help!

My lionfish gets ick I treat him and he is getting better all spots almost gone he's eating, I passed it off as stress related. This happened all in a period of 2 days. Day 3 comes along and everyone is doing good but my threadfin butterfly, he had little white spots(ick) in the evening and did not eat during feeding time. Everyone else ate and looked good. I wake up the next morning and everyone is DEAD!! My huma huma trigger,koran angel, lionfish, threadfin, Even my banded coral shimp.My anenome crab is good,my mushroom corals, button polys,red grape alge and kenya tree are doing fine. Can ick kill this fast??? What do I do now??? Should I just let the tank go fishless for 6 weeks to kill off the disease?

 

doesn't sound like ick to me, what are your water parameters?
ammonia
nitrite
nitrate
tempature
salinity
how long has the tank been running?

 

thanks amcarrig

 

Threads merged. What did you do/use to treat the fish?

 

Sorry about the multi thread. Not by my tank right now but to test again, yesterday all levels were good ammonia nitrite and nitrate very low test read 0, temp is always a constant 78.5 salanity is .024 (not in front of my meter so hope I said that right) this tank has been running for 5 months,I don't know what happend Any help will be greatly appriciated

 

for them all to die like that , all at once. could something have been accidently spilled into the tank? some sort of chemical or such? or if the lionfish died first overnight, could its poisons done this?

 

hmm, ok those all look fine, hows the alkalinity? do you dose anything? done any large maintenance tasks?
just looking for what may have changed recently to cause any kind of issue. Also, do you have a ground probe in the tank?

 

maybe stray electric? do you have a ground probe?

 

do you measure your salinity with a hydrometer?? if u do it could be way off, i had it happen to me and i believe it was the cause of my ich outbreak. sorry to hear about your loss..
