White Mark on Lineatus Fairy Wrasse - Ideas?!?! (Video)

[nuxx]

That sucks, sorry for the loss Peter. What was your take on the paraguard? I have dosed it like seachem recommends and for 30 days and after using literally liters of it I'm sure it really does what it's suppose to. I like it for dips prior to QT but I question the effectiveness of it for irradiating disease in a tank even after prolonged use. I was a day away from having the 5.3g or whatever it is drop shipped from seachem.. At 240$ I opted not to, and lack of effectiveness (at least IMO)

I've sort of changed my opinion on it... not due to a lack of it being effective, just due to my paranoia.

I've run 4 batches of fish through a 30 day routine of Paraguard and haven't had any issues.

On the newest batch of fish in QT (5 Huchtii Anthias and CBB) I noticed two white marks on one of the Huchtti Anthias' pectoral fins. Now these fish have markings on the same spots on their fins (normally orange / red) and this fish had white.

Since they are such active fish and a lighter color, I couldn't 100% say these marks were just markings.

This doubt pretty much made me rethink my personal QT procedure. With these fish I just started them on Cupramine for 30 days.

From now on I'm going to do the following with QTing fish:

1. Get fish used to the tank and eating.
2. Start a two week routine of ParaGuard with 3 rounds of PraziPro at the same time. Run a water change after 3 days of each Prazi treatment and redose on the 5th day.
3. Then do a large water change and run Cupramine for 30 days at around .35-.40 brought up over 5 days.

I just have too much dollar wise in fish in the display to even consider chancing putting a sick fish in the tank. I know it might be looked at as treating for nothing, but I'd rather know I treated for everything proactively.

Also I think the 2-3 week period before starting Cupramine will give the fish a better chance of making it through the treatment. The CBB is taking it like a champ, eating just as aggressively as the anthias.

I also think since ParaGuard and Prazi can be used at the same time (done it a few times now), it's a great catch all before running Cupramine.

IMO, I do not think that would have helped.

Do you think the fish was just doomed in the tank?

The Crosshatches and Tangs are in the tank with a pair of Flame Wrasses, Cleaner Wrasse, Black Ice Clownfish, Pajama Cardinals and small Lyretail Anthias and nobody gets picked on.

Only this Lineatus seems to have been the target of aggression. It has always hid and only really came out for food. The other fish that does that is the Chevron Tang, but it is not a shy fish and probably the most aggressive of the Tangs to each other (although being the smallest)... not aggressive, maybe brash is the right word.

Do you think the other fish could pick up on the Lineatus being timid and took it further? Wondering that having a female (like the Flame pair) would have just made the Lineatus more social and less likely to get picked on...
