Kole Tang Died

[Fumbles]

Little background:

90gallon tank mixed reef

I had been watching this tang for a couple months at the fish store and decided to get it. I bought it March 2. I didn’t quarantine because I don’t have much else in the tank. Just 2 ocellaris, gramma, and a ywm goby. Tang was stressed but found a comfortable spot. Took about 5 days before it wouldn’t hide when I walked up, but still shy. I feed rods food/mysis and ocean nutrition pellets, but for the tang I was also feeding nori with a rock and rubber band. I watched it close and it acted healthy while eating and pooping a lot. Couple days ago I noticed it was swimming as normal making the rounds, but also making a 5-10 second stop at the peppermint shrimps cave. Over and over. I also noticed it had what looked like bruising on one side of its belly, small though. I don’t think it was black ich and this was the first I had seen of it.

Now I did a dose of Chemiclean 48 hours ago to get rid of some cyano. It was an under dose of 8 level scoops(80 gallons). My tank is about 115 total. Left left all pumps and skimmer on and let it overflow back into tank. After 24 hours fish and corals happy. This morning(48 hours) I came down to do the big water change and I see the Kole laying on the sand, kind of faded and dead. Everything else seemed fine.

Ammonia and nitrates tested 0

I’m not blaming the Chemiclean, but could this have caused it? Was I just not ready to keep a tang and keep it healthy?

Thanks for reading and I can answer any questions.

Sorry about the loss. Beautiful fish. I would not think Chemiclean alone, but possibly a contributer. The stress from the move, O2 changes in tank from the Chemiclean. May have been more for him to handle than his immune system could compensate for.

Just a guess, but definitely sorry.

Thank you very much for the thoughts. It will be a while before I try another.

Sorry for the loss.

I dont know tangs well, but that looks suspiciously like a parasitic copepod.

Kole tangs need a high O2, turbulent water tank to thrive. Or just survive....

Adding a small power head near/aimed at the surface can help a crazy amount.

Chemiclean was most likely a contributing factor.

If your tank wasn't very turbulent to begin with it was already experiencing some stress.

I was using 2 mp10 anti sync on full power and my jebao 6000 return pump at 1/2 power pointed at the surface. I also have a gyre 150, but it was off because I was monitoring the flow from the mp10s.

I will keep this in mind for next time, thank you

It sounds like you have plenty of flow.

Low O2 can always be an issue, especially with some tangs.

But after learning about your pump/power heads I would say that wasn't the problem.

I lost my royal gramma too =( Was hiding in its cave for the last couple days, but I found it last night. I think my tank was way too young and I should have just waited it out. Goby and Clowns are doing fine. Cyano is gone and my chaeto grew almost 50%.

Realistically the Tang kept visiting the cleaner station in an attempt to have parasites removed. Can you post pics of the surviving fish maybe we will something and figure out what the culprit is.

 

[Fumbles]

I will get some pics of the others tomorrow when I’m home. Technically this tank is only 1 1/2 months old. The rock is from a 9 month old tank, but all new sand and water was added.

That actually makes parasites more of a reality. Just short of a ammonia spike that wiped everything out there isn’t much else in there.

I know there wasn’t ammonia because tests showed 0. Nitrates were 0 as well. I’ll report back if the others start acting unusual.

Update: The clowns look like they have some kind of bacterial infection, maybe Brooklynella? It looks similar to something I saw on the gramma when I pulled it from the tank. I have the day off tomorrow and can get some meds and set up a quarantine tank for them. The goby appears unaffected.

 

[Frtdrmrose7]

Looks like Brooklynella. I would do a FW dip ASAP to help buy time until you get meds. Brook is a quick killer. All fish will need to be treated and tank left fallow for 6 weeks.

Thank you, I did come across this is my searching. Will it be ok to put them back into the display after the freshwater dip, at least until I can get a steril qt tank up?

You can but you are re exposing the fish to a high parasite load in the tank. Any possibility of setting up a bucket to put them in after the dip? If not the dip should buy them some time.

Yes I can do a bucket, I have some fresh Sw made up. Thank you

I picked up some formalin and paragard from the lfs. Correct me if I was misinformed, but I heard that brooklynella is something that is usually introduced to a tank, not something that can randomly occur. The lfs suggests it could be some other kind of infection. Is it possible that the clowns suffered some type of chemical burn from the Chemiclean and are now affected by another bacteria due to the sores? Before the gramma died I noticed it had some open sores on its body, like I have seen on the clowns.

 

[Gareth elliott]

I have never seen a chemical burn from chemiclean.

You would see dead fish from asphyxia long before a concentration great enough to burn a fish occurred(if this is even possible)

Not sure paragaurd will work with brook also. And i wouldnt mix with the formalin. Seachem metroplex is another alternative for treating.

I got both treatments to have on hand in case I run into future issues. I’m not convinced I want to treat them with anything yet though. Does this still look like brooklynella? The reddish marks are what I’m referring to.
