Ich

There are 1000s of articles on ICH and I have read 100s. I have a 210 mixed reef with several different species of fish. I do not run a UV on the tank, I did 18w for about 1.5 years, never really saw any difference from an algae standpoint, just 1 more pump, 1 more buld and 1 more line to clean out so I disconnected. I feed the fish mainly flake food and occasional Nori (maybe 2 times per week). They all gobble up the flakes and I thought that due to the nutritional value this was the best route. All fish were in great condition. In Feb. I bought a Kole tang to add to the mix. There were a couple of Tangs in the tank so I expected a little bit of a fight. I bought the fish from a store that both treats and quarantines, cost a little more but I thought worth it. I then also put the tang in a 4 week tank prior to introduction to the main tank. The fighting between the fish was not as bad as I expected but within a few days the tank boss a PBT and the new Kole tang were showing signs of ICH. The PBT would periodically have a few spots here and there but never much more than that. I let it go a few days soaking the food in garlic hoping they would beat it naturally, they did not. It got worse and I started a treatment of KICK ICH. I used this a couple of years or so ago when I introduced the PBT and it seemed to do the job. I tried it again this time 2 complete treatments, it did not get better just slowed down the getting worse. I lost the kole tang (today), the powder blue (Saturday) and a flame angel (sort of surprised since it has scales some time last week). I started treating with "no sick fish" on Friday.

My conclusion - there is ICH in the tank, running a UV for nearly 2 years did not knock it out (which I would not have expected). The fish in the tank obviously built up a bit of a tolerance or immunity to it, stress from the introduction of the new tang allowed it to expand.

My rabbit fish and purple tang show little signs of it the cleaner wrasse is picking at them a little, clown fish looks as though he is going to go next.

So - now that it is in there, how do I ever get it out?

I ran an 18w UV on a Mag 5 for nearly 2 years, not to mention I think the odds of counting on every single floating parasite to flow through it is like winning the lottery twice - not likely. I think the UV may minimize but not eliminate.

I am only a so/so believer in the let their immunity system fight it off theory, I believe it had been in the tank and they had been fighting it off but the additional stress made it more than they could handle - just my theory.

Other than catching all of the fish and hoping to starve it out - not that I think for certain that would work either - what to do?

package,

In reading the timeline of your problem, I would be more suspicious that the new tang brought the Cryptocaryon into your system as opposed to it having been there all along. There are lots of opinions about "chronic ich" and systems that can seem to have it in low amounts for long periods, with occasional flare-ups. Still, no quarantine process is fail safe, and I would look towards that as being the vector that brought the ich in, combined with, as you noted the stress from fighting.
Its been my experience that during an outbreak, once you start to lose fish, it is difficult to prevent additional losses even if you begin an aggressive treatment with copper, etc., due to the time it takes the treatment to get started. I also feel that once the Cryptocaryon infection hits the moderate level - say 20 visible trophonts per fish, it is time to bail on using any partial or "tonic" treatment such as garlic, probiotics, UV, reef safe cures, etc.

The only reason that I was thinking that the new tang did not introduce it was because of my copper quarantine, LFS dipping and the fact that I would see what I thought were mild signs of it from time to time on my PBT.

Either way that $30 tang cost me $150 in fish, likely $150 in SPS coral (due to extensive reef safe treatments with no carbon or skimmer, less close monitoring), 3 bottles of KICK ICK at $20 a shot, an overnight shipment of "no sick fish" at $77.

Nice - nearly $500 in a raggy Kole tang that is now dead, expensive lesson.

OIC - when I read that your PBT had a few spots of ick, I thought that was AFTER you added the kole tang. If it has been showing signs on and off, then you probably had a chronic case going all that time and the aggression of the two fish was enough stress to cause it to go acute.
