Sick damsel

[Reef Breeder 2013]

Just today I bought a Yellowtail Damselfish, and it looked good in the LFS and in my tank, but about 1 hour ago I saw something white that it didn't have. I'm very worried right now. I've already tried to get her out, but I haven't been able to. So far I suspect it's Brooklynella, but maybe you can help me. Do you think Seachem SulfaPlex can help medicate her?

Sorry I couldn't post it here, so I uploaded it to Youtube and sent the link.

I see what may be a small scratch and could be from netting the fish at LFS.
Did you acclimate fish and how and how long?

 

[Reef Breeder 2013]

I acclimatized her for almost 1 hour and a half.

It appears to have some sort of whitish scratch on it, keep an eye on it over the next few days. Too much acclimatization time.

Do you know the salinity it arrived at versus that of your tank? Acclimating from low to high can be tough on the fish. Did the pet store have any trouble catching the fish? I agree, this looks like an acclimation issue plus damage from transport.

As jay asked, how did you acclimate? (drip, bucket, checked/matched numbers, etc)?

I put a little water in it with a pipette every 5 minutes.

Well, the LFS where I bought it is known for being one of the best saltwater aquariums in my city. I have the salinity correct, and I assume the salinity in the store was also correct.

Ok, I think it was a false alarm and it was simply her mucus, because if you think about it it would be strange if she went from being perfectly fine to having white spots.

Ive never heard of this and inadequate acclimation may have played a role. There are several ways to acclimate. Here is how I do mine:
Acclimations boxes are best used for pre-introduction and should not replace quarantine. it allows other occupants to become acquainted with new occupant and also to see if there is a potential fish that will oppose the new arrival. I float my bags to adjust temperature and then empty contents into clean buckets then add tank water to adjust and equalize salinity at minimum. Release under LOW light before lights out. Fish in shipped bags produce carbon dioxide and ammonia. The carbon dioxide lowers the pH of the water in the bag

Here is one of the most used methods. The process is:
The bag containing the fish floats in the aquarium. The bag is then opened and placed on the edge of the aquarium to prevent the bag from tipping over and the fish from jumping out of the bag. After this, using a glass, pipette or some other container, add a little water from the tank to the bag every 5 minutes. After about 1 hour (this is usually how long it takes to equalize the parameters), the fish is removed from the bag. I use this method for both fresh and salt water, and many aquariums I know also use it to acclimate fish to their tanks.

The problem is that "a little water" isn't quantified. Every five minutes for an hour is 12 additions. If the bag holds 300 ml of water, each addition needs to be 25 ml just to equalize the water by 50%...only halfway there. Here is my article on acclimation methods, it reviews a variety of methods"

Ok, I'll take a look at it.

False alarm, I just discovered that he simply had some sand stuck in his fins.
