Sick yellow tang

Hi guys,

I made sure to quarantine my yellow tang for over a month before introducing him in my DT. He seemed fine and ate well so I didnt treat him with copper or any other drugs while I was suspecting him to fall sick with ich. Hes actually my first fish for my DT. Yeah I know its a MAJOR mistake. I should have bought him last instead.

So I transferred him into my display tank and he seemed ok for about a week.
I noticed that he had a tendency to hide in my live rock and come out to eat the nori attached to my clip. I think this behavior is normal since hes just trying to know his surroundings and hes the only fish around. BTW this tank is a 75 gallon tank. I know...I know too small for him. I dont want to get into that debate in this thread.

Currently all he does all day is swim right in front of my Ecotech Vortech pump as if hes trying to surf the flow and has refused to eat anything. It looks funny to see but I think it has something to do with trying to relieve himself of something with the hard flow in front of him. This morning his end tail had rot, well two tiny pieces came off. Ive been reading Randy Holmes Farley article and decided to check my ammonia levels. Im using the Seachem Ammonia tester with these small yellow capsules that float and change to another color when you apply the reagent. A small green strain appeared on the capsule to my surprise. I think I might have some ammonia in my water. I did a water change yesterday and replaced the carbon as well. Now im wondering if he wasnt poisoned by the ammonia. This tank has been cycled for over two months and All of my readings were good so I didnt even bother to check my ammonia and nitrite again. I did monitor my nitrates which were below 5.

I had a ground probe also in my sump which I removed immediately. Im also suspecting stray voltage affecting him like Randy Holmes wrote in his article. He would suddenly move and stop while eating as if paralyzed by something and then suddenly run into his cave as if something bit him. Really weird behavior as if he was being shocked or electrocuted. Or maybe the Ammonia was affecting him.

Now Im trying desperately to make him eat. Ive dipped the Sea vegigies into Garlic Guard to draw his attention but he just ignores it. All he wants to do is swim in front of flow. I think hes swimming to his death since he wont have energy anymore if he continues like that without eating.


Another sign why I didnt bother looking at ammonia levels were my snails behavior. They all seemed to be doing fine and grazing at my LR. I thought they would die if ammonia levels were detected. I was wrong....

Im planning to do another big water change in a few hours. Is it too late for my YT? LFS and online stores write that YT are easy to care for. They are wrong...from reading alot of articles on them they should be re-classified as hard to maintain and not for beginners like me.

I have filmed him today. Here is how he looks

Doubt it's your ammonia. In my experience 4 weeks isnt enough time in qt. however tangs are such ich magnets that you should just put it through TTM regardles if you see signs are not. The moved to the display which is a new environment gave the parasite a chance to really take over.

Is the tang flashing/ scratching? When they swim like that infront of flow is to find relief for whatever is feeding on its gills. I think its ich but theres a chance it might be velvet. So have to try and rule that out.
 
Well I woke up at 4 am to check on him and he was on his side and at the bottom of the tank with his gills not breathing and no reaction from netting him. His problems are over. I had a feeling transferring him to QT would have given him a shock since he was so weak without eating for 24+ hours. Quite disappointing and frustrating.

I should have acted more quickly I guess. Now what can I do with my DT? Let it go fallow for how many months? I only have a few inverts in there. Can I continue growing my clean up crew and have a few sps or mushrooms in there without fish? I don't feel like taking down my whole tank...I'll wait it out instead.
 
I am not sure you had ich; the mortality and behavior sounds like velvet. Sounds like your LFS runs a low level of copper. That means you must quarantine for a minimum of five weeks. And going forward, please buy fish appropriate to your tank size as it will prevent a lot of potential problems.
 
Yeah lesson learned with tangs. Even if I had an even bigger tank I dontt think I would get another one. They seem too fragile and squishy to live in any size tank.

Nope. Yellow tangs are pretty much bullet proof as long as they are quarantined and disease free, and in tank over 75 gallons. I'm sorry about your loss.
 
Well, I've been monitoring my ammonia with a Seachem tester after my Tang a few days ago and somehow it looks like I'm having a cycle since Ammonia is being picked up by my tester. Now I'm really wondering if I didn't poison the poor little thing without knowing it. She might have had velvet as well but I made it worse with my ammonia levels.

I can't tell how much ammonia I have since this is a color scheme and doesn't give me proper readings. I think I'll get an Hanna reader instead.

What can I do to reduce the ammonia fast? I used Prime a few days and it seems to bind the ammonia for a day but that's it. I never thought I would go through another cycle like that...this is so weird...



Do you guys always test 0 ammonia in your tank? I did another water change yesterday
 
Ammonia should be 0 at all times. What name brand test kit are you using? If you are using API, they give off a false reading making it look like the test results are 0.25ppm I personally like Salifert for all the ammonia, nirite, and nirate test. Yellow Tangs are very hardy. They have to be provide with a good quarantine process, good diet, and the appropriate tank size.
