Quick info on my tank:
30 gallon
(4 months old since cycle)
5 fish - maroon clown, oscellaris clown, chromis, and the two new dottybacks
Products I often use - seachem prime, API conditioner, seachem pristine, market distilled water to top off tank from evaporation.
Salinity - I usually have it between 1.024 - 1.027

Hello, I just recently purchased two new dottybacks a couple of days ago. I acclimated them in a bucket with their original water and then slowly added my tank water. The whole thing took about two hours. I received them at night so it already was naturally very dark in the room. They looked in good health. No signs of any damage or stress during acclimation. They calmly hid in the PVC pipe and would occasionally swim out for a brief moment.

The following day I noticed they were flashing once they left their hiding spots. I became very concerned because I've read about how flashing is a sign of stress and could also indicate disease. In a panic, I did the baseline tests of parameters. I just ran them again this morning and here are the pictures.

The pH was 8.0 (I forgot to take a picture of that one)

My other fish aren't flashing. It's only the two dottybacks. I am very concerned about their health. I feel very bad. I just impulsively ordered Prazipro thinking maybe I have some type of parasite in my tank. Any suggestions as to what I should do in this situation would be greatly appreciated - I should note that I do however, only have one tank at the moment, so Im unable to do a true quarantine tank setup. I do plan on investing in one very soon now that I see it's value but I doubt I'd be able to set one up quickly enough to help in this particular instance. Regardless, thank you for taking your time to read this and maintaining a great forum here as well.
 
Any white spots on them.
 
What specific behavior do you see when you say they are "flashing" - can you describe it?

Any other unusual behavior? Are they eating?


Is there discoloration or spots on them?


Those params look ok, although in a cycled tank I would expect to some nitrates. In my experience API usually gives a questionable false positive.
 
Ah good point - I shouldve taken a picture of them. I don't think I see any spots on them but I am very new at this. I still very much have an untrained eye but it doesn't look like they have any external sign of disease at the moment no?

Ah regarding the flashing - they quickly swim towards the bottom of the tank and then thrust their side on the sand. They'll do this two or three times in a row and then swim back to a hiding spot. Then maybe a few minutes later they'll repeat the process.

They also swim very fast and frantic, as if they're constantly being chased but I don't see the other fish even swimming remotely close to them.

I dropped a few sinking pellets in the tank this morning and yesterday morning. I saw them both snag a couple but that was it. They ignored the flakes and brine shrimp that I put at the top of the tank. The other 3 fish gobbled that up. So I would say, they ate but very little. I dropped more pellets in the tank just now but they don't seem to be going for them at the moment.
 
Flashing is generally a sign that there is something on the fish bothering it. Could be ich, velvet, flukes.... Can you get any up close pictures of the fish that are flashing. Usually it's them trying to scrape or knock off a parasite.
 
The scratching on the stand is concerning but the rest sounds like it could be normal. My dottyback is sometimes very active, other times not.

Since you dont have means to set up a QT and there aren't any corals visible in your tank maybe watch and read up on hyposalinity. You aren't going to want to put copper in with your rocks.

Hopefully someone with more experience than mine will chime in.
 
I have a bi-color blenny that flashes some every day. He did have a bacterial infection because he got beat up by my dottyback. That was 5 months ago.

I set up a 10 gallon as a HT. I bought a cheap metal stand and HOB filter. You could sit it on a kitchen counter or desk or something. The bucket would work but you cant observe the fish to tell what is going on.
