DT has ich. Just bought new fish and theyre in QT....please help

[Wowkuh]

I had a 1yr old 100g then upgraded to a 180 and the 180 been up and running for 3months, all the rock and water was moved to the 180.

The only fish that made the transition to the upgrade was a cardinal. So I now have a 180 running for about 1month. My water tested good and was cycled so I decided to add new fish all at once. I added 2 blue green chromis, and 4 tangs. PBT, sailfin, purple tang, blonde naso. Someone had ich, and since I didnt really have any fish in the tank beforehad, I chose not to QT and just drip acclimate and add to DT. Well here i am with ich in my DT and plan to let it run its course and let my fish develop a strong immune system. With good quality food, stress free environment, and great water.

I just came back from vaca in socal and HAD (not really lol) to buy fish from a reputable LFS. Anyway. Do y'all see a point in QTing the new fish at all? My MAIN concern is adding marine velvet to the whole tank from the new fish, not ich since my tank already has it. As of now. The new fish are actually in QT. what should i do? Stick with the 4-6week QT or just throw them in since I already have ich.

Quarantine them. If you get the nastier stuff like velvet, uronema, and others it's goodbye other fishes.


I've been ichless in my display for 2.5 years quarantine all my fishes. So ones day I added a small colony of Walt Disney acro and a few days later my tangs started showing ich. I'm just going to let them fight it as getting everyone out well stress them out even more. I currently have a bunch of fish in quarantine. Not for ich but there nastier stuff like velvet.

OK cool. Thats what I was thinking. But since velvet is faster (as far as killing fish) wont I see signs faster? Therefore I can QT a shorter time? Basically if they don't die in a week

I have low level ich in my system, but I still QT all new fish. Certainly to avoid things worse than ich (velvet, brook, uronema, flukes as mentioned), but also to avoid adding another, potentially more virulent ich strain. Although a new, QT'd fish sometimes (though not usually) shows a few spots, they always go away after a week or so and don't return.

Alright. So I guess I'll just QT them for 4-6 weeks.

Great advice from Scuzy and Simon. I would QT for 6 weeks minimum
