Basic tank acting odd

[bpace96]

I have a naso tang that I have recently quarantined as a precaution. I had some Cyanobacteria growing in my grass and use a dropper chemical to treat it as instructed by the store owner and the bottle. Did my water change and all my fish seemed fine. I tried to feed that night after the water change had settled and my tang wouldn’t eat. Just came to the top of the tank as usually as if she was waiting on me to feed them but didn’t seem to notice the food going in the tank. So I just let that slide thinking she wasn’t hungry. The next day I noticed her laying on the bottom of the tank under a rock. I went to pull her out thinking she was dead and she started moving but not fast or much. Put her in my quarantine tank and she’s just been barely swimming and laying around. She’s still moving her eyes around but will swim tilted up or down and just lay against a rock and still won’t eat.
I have a mason tank, snowflake eel, sapphire damsel, hermit crabs, snails, and a couple turbo snails.
thank you in advance.

How long has the tank been up? How long have you had the tang? What size system is it? How large of a water change did you do? How many other fish in the tank? Any other fish showing signs of distress?

What chemical did you use for the cyano?

What chemical did you put in the Display Tank? How long have you had the Naso? Are the spots in the photo on the fish or on the aquarium glass?

I have a 75 gal with 2 other fish I do about a 25-20% water change and I have had the tank for about 1 1/2 years. We had the tang for about 6 months and never had any problems also my other two are doing just fine. The spots in the picture were just stuff on the glass. She did finally pass today while I was at work but she had lost a lot of color on both sides. The stuff I used was chemiclean

 

[gbroadbridge]

Sorry to hear.

You need to add a lot of extra aeration and run the skimmer without a collection cup when using chemiclean. You didn't mention whether you did that.

You didn't say the fish was gasping, so maybe that wasn't the problem anyway.

I don’t have a skimmer and I’ve been thinking my other fan isn’t big enough.
she hasn’t been gasping but breathing normal and that’s what threw me off. She showed no irritation just swam weird and laid down.
Thank you tho. She just went to fast
