fish problem

i have 9 fish in my tank 1 kole tang 1 naso 1 yellow tang 3 4 stripe damsel and a maroon clow ans 2 engineer gobies. this morning i wake up and the kole tang is dead stuck to the korallia ph. now my yellow tang has a big white spot on him and he looks like he is turning white!

i know its a disease or bacterial but can anybody give some info on how to help him?
i have a mixed reef and cannot catch him or trap him. im gonna try and get him just at feeding time but he’s not really eating but just a little bit.

any and all help would be appreciated! i know its not ick

Sorry about the loss of the Kole.

My old yellow would “pale out” when it was stressed - I think they all have the white spot, sometimes it’s just more visible then others.

Is it possible to get a pic of the fish so we can get a better idea of what you may be dealing with?

:-?just lost my scooter blenny had both these fish since i started the tank. dont have time to test till tonight but i did a 20 g wc

Sounds like Amyloodinium ocellatum (marine velvet) to me. Have you added anything recently to the tank? What are your water parameters like?

or any chance of a toxic hydrogen sulfide release from a sand bed. done any stirring or moving lately? or got a dead flow area full of muck?

Tat you should know the drill by now. First question anyone is going to ask you is what are you water parameters.

Have you moved rocks around recently? Added animals? Been on vacation? Had someone else feeding? Dug up sand? Made any major changes? Basically what is the recent history.

Take things slow as you could just be adding fuel to the fire if you do too much. If you are given advice make sure you trust the source and what you are being told and what it is you are going to do. If something doesn’t make sense ask for more info or do more research on your own. Usually only bad things happen quickly.

If Nitrates are the problem adding more food could only add to the problem if you are not doing your water changes properly.

Post more details and we will try to help. Can’t really give too much advice at this point.

My nitrates are red as blood!!! my ammonia is .50 my ph was normal mag is normal calcium normal alk normal.

The only thing i did was change water 20 g but i changed salt from reef crystals to coralife salt in a bag cause i was broke! i only had a lil bit of that salt left and i just mixed it up tested it it tested 20ppm of nitrates and .25 ppm of ammonia. i didnt test for calcium in the new salt.

Has any body ever have salt with nitrates in it? freaking me out cause i tested it twice

What is ‘normal’ for calc, alk and mag?

Check your source water as well (the water you are mixing the salt with) and verify it is coming from your salts and not the source water.

Also what are you mixing it up in?

i just tested the source water and it test zero

Did you test with a freshwater test kit or your SW test kit?

salt

I am not 100% certain and I am hoping one of chemistry experts chimes in, but I think the salt and fresh water test kits may be different.

So if you are testing fresh water with a SW test kit you may not be getting accurate results on the source water.

I would be surprised if the salt was a problem, but it is possible. If money was tight I would have waited a week to get a good salt and left the tank without a water change. If it badly needed a water change and had been without one for a while and you haven’t had the money to take care of the tank for a while it may be time to consider selling off some of the messier eaters in your tank. It can be an expensive hobby and time after time many people on the forums find it too expensive and sell of parts(if not all) of their aquariums. If you would like to keep the animals you’ll want to decide how much of a priority it is and get a good quality salt and do frequent small changes.(15gallons once then 10 gallons daily night for a week would be my recommendation. 90gallon tank right?)

As Criag said run tests on your source water to see if the water has problems before you even add the salt.

As far as fresh water test kits vs SW test kits I doubt that is the problem.

I hope we can help you Tat. That is why some of us are on this forum.

I disagree. I’ve used coralife salt for a couple of years, with no ill effects. I believe that it is of equal quality to Instant Ocean. I certainly don’t think that the salt is to blame for fish death. Did you change the way that you mix your salt? Do you have dead corals? Typically your corals would die off before your fish if there were issues in the water. 50 ppm nitrate is not high enough to kill fish. The only possibilty is that the nitrate spike killed off a coral (or stressed it to the pont of releasing toxins) and the toxins killed them.

I believe CDangelo is correcton salt tests not working for fresh water.

Do you age the water before you change it? If not, it may have been low in oxygen. If you have a decent bioload, that could off your fish.

All opinions, and just trying to help. Hope it all comes back to normal for you, man.

Sorry I didn’t think of it earlier when I was first reading this thread - having 2 fish die in the tank in relatively close proximity will cause a small cycle so I am not surprised at the levels being elevated in the tank itself, the fresh salt water having detectable trates makes me nervous though.

well, dropping two deadies into the tank for a night wont spike the readings. that may take a week or so as it progressively degrades. im sure Jim fished out the floaters soon as they died. or next morning for sure. Im pretty sure he knows what a floater looks like.
