Brooklynella questions

In Memoriam
I had a false perc die from what I figured to be brooklynella about a mont ago, he was the only fish in the tank. The tank has gone about amonth without any fish until last week, I added a new false perc. The new guy is not eating at all and I'm worried he may have brook. Do you think the brook would have survived a month without a host? Do you think the new fish is likely to have brook?
 
It is almost impossible to accurately diagnose brook without a wet mount of skin or gills.

Here is a method that oama suggests to distinguish between brook and amyloo

"Your best bet is to remove the fish and place them into a Hospital tank. Do a 1-2 minute FW dip on them in a clear dish/bowl before adding them to the H tank. Remove ALL the fish from the reef. You can not treat a reef tank with anything that would not have some type of ill effect (at least to my knowledge/experience).

If you saw white spots on the fish, like grains of salt, you most likely have crypto. Treat the H tank either with Hyposalinity or copper.

If you did not see "grains", look at the FW dip bowl, after you removed the fish. Swirl it around to create a vortex. Do you see any whitish particles piling up in the center of the dish? Like a pinch of talcum powder was added to the water. Then you most likely have Amyloo. Hyposalinity will not work. Use copper.

If you see nothing in the FW dip water and/or see sloughing of the slime coat, you most likely have Brooklynella. A Nasty bug. This can be treated with prolonged FW baths (not a short dip, more like 30 min to 1 hr), but often in advanced cases, the fish may not survive the bath. Use Formalin ASAP, particularly if you see the slime coat sloughing (sign of advanced infestation). Treat the H tank with 1 ml formalin per 10 gal for moderate infestations. 1 ml/5gal for more drastic cases. You can switch over to 1/10 after you see some improvement in your fish. Treat for at least 10 days. But keep them in the hospital tank for a full 3-4 weeks while the reef tank remains fish free. In really serious cases of brook, you can do a SW (as in saltwater) bath with formalin @ 1ml/1gal for 1 hour."

Brook-causing ectoparasites have no free swimming stage. Supposedly, if you remove all boney fish from the system, you end brook life cycle.

The longest documented survivor in a fishless system is ich - 72 days.

Do yourself a favor and QT all new fish for at least 4 weeks.
