Glass half full?

Last Saturday i noticed that all my fish in my tank started showing signs of oodinium. i started treatment stright away with freshwater baths and adding what was sold as a reef safe oodinium treatment too my tank. anyway, a week later i am only left with a sixline wrasse. the good news is all my corals and inverts are fine. ok my first question is, is there any reason that the wrasse hasn't yet and isn't showing nay signs of the parasite? do they have a thick layer of mucus or something protecting them?

now, instead off focussing on the bad side of this, i decided to look on the bright side, as a chance to come up with a whole new stocklist of fish. my tank used to be a peacefulu reef tank, it had a brownbar goby, a tomini tang, a pair of occelaris clowns, a sixline wrasse and an eibli angelfish (i belive he brough the parasite.) anyway, how does this sound for a new stocklist, by the way my tank is a 55g with a 20g sump/fuge and a skimmer that runs 24/7,

2 x maroon clownfish
1 x radiata (or ohter dwarf lion fish)
1 x arc eye hwkfish
1 x sixline wrasse

my second question is will these fish get along together, and mainly will the sixline get bullied? any opinions are appreciated

cheers,
Daniel

When was the Wrasse introduced? It may have been the carrier. Fish can develop immunity to Amyloodinium when exposure doesn't kill them. One way or another, I suspect the Wrasse is immune. That's a double-edged sword tho since it probably means that the Wrasse will carry it in tank without hospitalization and allowing the tank to lay fish-fallow.

The Sixline should be fine with your stock list with the exception that the Lion is predatory and will eventually grow large enough to consume it.

Is there any way of making sure that the parasite is not in the tank, even with the wrasse? If the wrasse is immune could it still carry the parasite? I plan on leaving the tank wiht only the wrasse in it for 8 weeks, will this kill off the paasite, or will it still be on the wrasse?

KDodds, the wrasse has been in the tank for about nine months, the reason that I think that the Eibli introduced the parasite is because it was the last fish/coral/anything added ot the tank.

Any other comments on the stocklist are more than welcome.

Cheers Daniel

P.s. I just re-read my first post and I would like to apologise for the poor spelling and grammar, it was about 1:00 here when i typed it.

If you want to be sure you got rid of the parasite, take out the wrasse, place it in a quarantine tank, treat with copper, leave the display fishless for 6-8 weeks, and quarantine all new additions.

With the Wrasse in? Without treating the entire tank? No.

Yes.

Impossible to say really.

Funny thing about infecting agents like Crypto and Amy. You never really can be sure where they came from. For instance, even if you're QTing, if you're not treating for the pathogen, it's possible that the fish can be asymptomatic in QT, yet still carry the pathogen into the tank. The remaining fish can also remain asymptomatic until something (usually a massive change) happens. For instance, fish can be fine in the main tank for months and months after the last introduction. Then, a temp spike occurs and the Tang becoems symptomatic for ich.

Thanks for the quick replies, what do you guys think the best treatment for this would be?

IF it's Amyloodinium, I believe the recommended protocol is Cu treatment. Steven would definitely know better than I would.
