Possible ich in large reef

[dcinky]

I have an established 200 gal reef aquarium that has had the same stable of fish for a number of years. When recently replenishing the CUC I overlooked the possibility of introducing disease and added the inverts directly into the aquarium after receiving them from the supplier. It now appears my once beautiful, healthy fish are coming down with what I believe is ich. Some of the animals have grown to be extra large. I haven’t had a QT set up in years. I’m so disgusted. Could you please provide your opinions on the best way to handle this emerging serious problem, I could definitely use some advice. Thank you!

While not impossible it seems to me that introducing ich from a cuc is unusual. Are you sure it is ich?

Can you take some pics of the fish so we can get some eyes on it and help you with a game plan. Sorry your going through this...

Edit- how long ago did you introduce your Cuc and how long was it before you started noticing the problem?

Although there are rare cases on inverts introducing parasite into system, there have been instances, It can be assumes coincidence, but not to be ruled out. I would start with PraziPro which is effective and reef safe, but first Verify it IS parasitical before treatment. As others suggested, any close up pics in good lighting will be helpful in evaluation to what you are seeing in your tank

CUC went in on January 10th. Noticed possible problems the 24th. I’ll upload pics soon as the lights cycle on. Appears to be spots of whitish discoloration or possible small bumps on the bodies of many of the fish

+1 pics would be helpful.

As for treatment/management options, it would depend on what it is but if ich or velvet the only way to eradicate would be to remove the fish and treat.

Depending on what type of fish you have, you may just be able to monitor them and see if it improves on its own. Most well established fish can’t fight off ich. Quarantining that many large fish will not be an easy task.
