Should I treat for Ich or not?

[rhymechizel]

My 150g tank is about 3 months old and about 4 weeks ago I ordered around 10 fish. Two week ago the naso tang had a few spots that looked like ich. He came with some scatches so it was hard to tell if they were ich or scatches. He has been a good eater and active. On Friday the 24th my blue tang showed two spots and on saturday the 25th my flame angel had one spot on his tail. Today the 27th the blue tang has zero spots and the flame angel spot appears lighter. The naso is still hard to tell but he does have one obvious spot on one fin. All my fish are not showing any other signs other than the white spots I mentioned. I have been running UV before I had fish and while they have been in the tank.

My question is should I remove all my fish and treat them or let them ride it out.

Most if not all fish will die from ich if you do nothing.

The UV sized against viruses and bacteria will not control ich. I always use UV for the first two months in QT for new fish against external bacterial infection, not intended for ich. There is possibly or even likely a high enough wattage of UV against ich, but not an ordinary sized UV.

Did you put all fish in QT or DT?

It takes some skills to overcome your situation.

As far as ammonia in a tank is concerned, a 3 month old tank may or may not handle all the ammonia. In fact, if the medium in the DT tank (often the rock) had been robustly cycled, then after 4-5 weeks it will process practically all ammonia of any bioload. But if the rock has not be cycled robustly, even 5 year-old tank will not support ten medium sized fish when suddenly added.

If your rock is still free of encrusted lives, you can try hypo in DT. Hypo will kill off most encrusted lives on rock and could pollute the DT and overload the biological filtration.

You should also, ASAP, start a robust cycle with enough medium for biological filtration in a separate container.

You sound quite green at this, so your chance of overcoming this problem is not good, I am afraid to think.

Fish went into Dt not QT. Although I am going to do QT from now on. The naso and flame angel were the only two large fish. The rest were small; Catalina goby firefish small anthias and a few others. The rock had actually cycled in the tank for a year with just a power head. The tank has had lights and filtration for 3 months. I have had undetectable ammonia with my Red Sea test kit since I added the fish.

As I said, first consider whether it is possible to treat in DT.

If the tank is FO and the rock has no encrusted lives, you can try hypo.

Any means to treat against ich in DT can kill off lives to pollute and overload biological filter.

You can try Amquel or Prime but have to be sure about drug interaction. Hypo with Prime or Amquel may work if your DT is FO and does not have very much encrusted lives.
