I have always seen the odd spot on my blue tang but never gotten out of control.
The rest of the fish are still fine and the tank is responding well so just have to wait and see as i cant fit all of my fish in qt

Everything I've read indicates ich is quite rare and not a problem in the ocean.

This always gets people miffed when they hear this but, my sons tank got a terrible outbreak if Ich twice, two weeks apart, from adding a only one pound of sand/grunge that was ordered online and had a chance to cool way down during shipping.
I say Ich lives in the sand also, is always present, and it just waits on a stress factor to hatch and attach to fish. |

So really, that wait six weeks will be a pretty good period of time for even the trophots to die off for lack of a host? In the sand? What I believe was my precipitating event was after I brought in two gold striped maroon clowns, a powder brown and yellow tang, I completely stirred up the sand bed trying to get algae from the glass beneath the level of the substrate. Two days later, fish started succumbing. The powder brown was the first to go.
Started using the 5-nitroimidazole in the tank, after reading the Captain's suggested reading, but now only one fishy left. Need QT to get him out. Then, I guess, the waiting just begins. Don't know if I want a whole 29 (that LFS wants to sell me - but not the usual guy, Rusty, who is way smart about reefs). But 10 may be too small to QT a decent sized, say, 4" fish or two... Thoughts? Thanks, Dave

Read my interests. I always QT after bringing home any and every fish and the only place I have ever seen ich on any of my fish has been in QT after a week or so. After hypo I have never had any ich in the main tanks.

The trophont stage is the stage that is attached to the fish and it lasts no more than three to seven days. The tomont (cyst) state is the reproductive stage and it usually lasts around a week but this can vary from three days to 28 days.

Let's review:
Tomont (cyst) stage usually lasts approximately one week but can be as short as 3 days or as long as 28 days. At the end of this reproductive stage, up to 200 tomites excyst. These can develop into free swimming theronts. The theronts are only viable for 24-48 hours, sometimes less. If they can't find a host fish to attach to during that time they die. The theronts attach to the fish and become trophonts. They burrow deep into the epithelium and grow in size. This stage lasts from 3-7 days. Mature trophonts fall off the fish (usually at night). This stage can be free swimming or they can simply drift straight to the substrate. This stage lasts up to 18 hours before encystment as tomonts. The tomonts (cysts) are the reproductive stage that usually lasts about one week but can be as short as 3 days or as long as 28 days. The cyst opens releasing up to 200 tomites which are capable of becoming free swimming theronts. Excystment happens at night.

Hypo is soooo much easier to do. Get your salinity down to 1.009 and make a mark on your tank at that water level, then all you have to do is top off to that same level a couple of times a day and check your salinity every day or two and you are all set. Sooo easy it's... priceless!!!

Copper has been proven to have long-term deleterious effects on the immune system and reproductive system, which is why many authors (e.g., Scott Michael) no longer recommend it.

Also with copper you have to test...test some more...add copper...test...add...buy more copper...test...etc,etc.

However, it is certainly possible to find fish available for sale that are not infected with ich. It is not ubiquitous in the wild. Studies have shown that the incidence of Cryptocaryon irritans varies and even in areas where it is more common, the parasite loads are small and not all fish are infected. It may be geographically related because the incidence of C. irritans appears to vary widely with some studies showing very few, if any, infected fish and other studies showing low levels of infestation to be fairly common. Study finding few, if any, infected fish in Puerto Rico: Bunkley-Williams L. and Williams E.H. 1994. Disease caused by Trichodina spheroidesi and Cryptocaryon irritans (Ciliophora) in wild coral reef fishes. Journal of Aquatic Animal Health 6:360-361. Diggles and Lester found low levels of infestation were fairly common in southern Queensland: Diggles B.K. and Lester R.J. 1996. Influence of temperature and host species on the development of Cryptocaryon irritans. J Parasitol 82:45-51. Diggles B.K. and Lester R.J. 1996. Variation in the development of two isolates of Cryptocaryon irritans. J Parasitol 82:384-388. There are older studies that also seem to confirm that distribution varies geographically.

I didn't read where ich only lives on fish.
Is it possible for it to live on/in microstars and micro organisms in your sand bed? I think it can. Better yet, I'll give this another go around---- Should you QT live sand that is out of another tank? |

Ich cannot feed off of anything other than fish BUT it can come in on anything WET. You should QT everything before putting it into the main tank although you don't medicate or perform hypo. The ich will die on its own in 4-6 weeks if you QT without fish.
