brooklynella questions

[jelwyoming]

I have a 120g reef tank that has been going well for about 2 years. Recently, I had some rather quick deaths of some fish, carpenter wrasse and eight-lined wrasse that I attributed to an alkalinity problem when my reactor overdosed the system somewhat. Recently, I have had all but one of my clowns (2 ocellaris and one maroon) die in a very short time when all was well. There was no sign of infection, feeding loss, just one day of rapid breathing and then gone!. I am beginning to think that perhaps one of the other fish carries brooklynella and passed it to the newer or more susceptible fish.
Can brook attack and kill other than clowns?
Can other species carry it and stay healthy?
Now that all but one of my clowns are gone and other fish appear very healthy, is there anything to look for that might indicate that the tank is still infected?
Should I assume that it will be infected for ever? If the one remaining clown survives for some period, would it indicate that it was something else? I had some temperature swings at this same time that may have stressed them. I am at loss at to what is going on since I have some more disease prone fish such as a yellow tang and a copperband that are doing great.
Please comment.

What are all the water parmeters now?

[jelwyoming]

ammonia 0, nitrites 0 nitrates 3 specific gravity 1.025, temp 77,
CA 430, alkalinity 3.45meq, PO4 .03ppm.
I run phosban, charcoal and a polish resin in a filter bag in the sump.
I found the body of the last clownfish this morning. There is no doubt now that it is brooklynella.

Any more information or help?

I think I answered in your other thread.

You told me that the parasite is transmitted fish to fish. If the others remain healthy, I QT another set of clowns and place them in the tank after that, is there still a good chance that they catch it again? I guess what I am asking is can the other fish be caring it but not show signs of it, or if they continue on fine is it safe to assume that it is gone?

No absolutes, but this is an opportunistic parasite that is usually not a problem unless the fish are weak due to poor water quality, poor diet or stress. Very common in newly imported or recently caught and transported fish. You will probably be OK with more clowns if you just quarantine them for 30 days prior to adding them to the display tank.

That explains more for me right there thinking about this. The brook hit right after my chiller failed and the temperature went very high (83+) along with my calcium reactor plugging, causing the alkalinity to go way off. Undoubtedly, this stressed out the clowns very much.
Thanks very much for the help, Terry.

I had brrok in my tank and I found out that it can attack angelfish. Interestingly I remember at the time of the outbreak some of my corraline algae turning white, come to find out it can do a job on certain algaes.

I am glad that I don't see that it mine. I just wish that it would attack hair algae instead!
