Losing fish to vortechs :(

Give her a freshwater bath and the black ich will drop off.
What is the size of your tank?

[dynamite]

I have a 90g tank
My Yellow Tang is quite small tho, like 2 inches?
I don't know if is Black ich.. he seems fine.. 2 days ago I added carbon and I didn't rinse it Do you think it may be some particles of carbon? How can I tell if it's black ich or carbon?

You really must rinse your carbon. There is a suspected link between carbon dust and HLLE. There was a study being done a while ago to validate this, but I haven't heard anything more since and I do not know the results. However, it's not hard to imagine that carbon dust could be very bad for fish.

Or just buy the Carbon from BRS that has minimal dust.

I don't rinse mine, what I do is just let the first few gallons of water run through it into a pale, and then when the water is running clear then I put the output back into the sump. In effect this is rinsing it, but it's much easier than trying to rinse it by hand at the sink.

Thanks for the info.. I'll start rinsing my carbon.

I think I'm going to give my YellowTang a fresh water bath.
He's hard to catch!!!
Would a cleaner shrimp or wrasse do the job?

Ok, so after half an hour of chasing my Yellow Tang and destroying my aquascape I gave my yellow tang a 6m freshwater bath to get rid of the black spots... and apparently they're gone. He's stressed and hiding And I hope he survives to this bad experience of swimming in freshwater.

I don't want to stress him more so I'll re-aquascape the tank tomorrow, I'm afraid to lose him

I also found my Candy Cane Pistol shrimp! I thought he died or something... Now he shares the same rock with my Yasha Goby but not the same entrance
