6 fish dead velvet or brooks

[connectionzman]

I have 6 fish dead already, I noticed some fuzz in my clown and then within a few days everything was dropping like flies, one thing I did notice with the puffer was it seemed like he had mucus like stretching behind him. I didn’t really notice it on the other fish and he was like faded or like a Matt color to him and he got really lazy,

Salfin tang dead
Purple tang dead
Foxface dead
Pufferfish dead
2 clowns dead
Domino damsel dead

The final video I posted is the rabbit fish, which is the last surviving fish acting extremely weird and the video of the purple tang the white grains are sand

Sorry, that's heartbreaking. When was the last time you added new livestock to the tank? Not a fish medic, but the symptoms you're describing sound like brook. If you can, take a clearer video of the foxface under bright white lights only, about 30s long. That will really help the fish medics make a proper diagnosis.
That said, I'm pretty worried it doesn't have much time left. Do you have Ruby Rally Pro on hand?

Far from brooklynella as these fish dont get brooklynella. I suspect velvet however, are there any inverts in the tank?
If so, and if theyre doing well, rules out water issue. If velvet, some signs you would have seen were fish will scratch body against hard objects, lethargic behavior, Loss of appetite and weight loss, Rapid, labored breathing, Fins clamped against the body, and typically stay at the surface of the water, or remain in a position where a steady flow of water is present in the aquarium.
Ich always shows spots at first.

Sorry to hear.

I presume the last fish has died overnight?

You'll need to leave the tank fallow (fishless) for 60+ days.

Just to clarify - only fish were affected, the invertebrates are all fine? (that points 100% to a fish disease).
Did you see rapid breathing or spots *before* you started losing fish?
Can you describe the "fuzz" you saw on the clownfish?

Pretty much everything in that tank died as of this morning. The only fish still alive are a diamond goby and a wrasse. I never really noticed any visible spots; instead, the first sign was a white, fuzzy-looking film on the clownfish. Later, the dogface puffer developed a slime trail that would trail behind him . I never saw a gold dust or peppering appearance on any of the fish — it was mainly just the fuzz and slime.



The fish also stopped eating, hid constantly, and avoided being in the flow. Water parameters were all in check, so it wasn’t a chemistry issue. From what I understand, Brooklynella tends to hit clownfish first, but it absolutely can go on to kill other species as well

I attached multiple videos and you can see what’s on the clowns

In that tank because I was not sure I did kick ich and rally pro

Sorry - the pics are too dark/blue for a definitive diagnosis.

Brooklynella can hit other fish, but an exact list of susceptible species isn't clear to me. Gobies DO get it though, wrasses do not seem to.
