Scopas Tang Acting Funny?

[ollysaquariums]

Hey all,
My Scopas Tang I just noticed has been hiding in the corner of my tank near the overflow box and just darkened its colour to blend in and just sitting there. What could be the reason for this and how do I fix it?

That powder brown in most likely the issues. They are very aggressive especially if it was in the tank first. You may need to implore some tricks like rearranging the rock work a bit or can trying the mirror trick till aggression sidelines. If have a sump and can easily scoop the brown out I find leaving them down there for a few days to be a good method then reintroducing

I also forgot to add that the scopas isn’t eating either. But the gold rim (or powder brown) was introduced with the convict about 2 months after the scopas so I’m not sure.

It not uncommon a gold rim and that species of tang to start to become more aggressive and territorial once it become more acclimated to the tank and it surrounding. Try some of the methods mentioned above. Get getting it to eat should be a priority. May need to move to an acclimation box.

It’s definitely not aggression because the gold rim is the most peaceful in the tank so I think it could be water quality.

What are your params. Is it breathing heaving may be fluke. Do you run UV and/or QT all your fish adds.

Okay so this is the thing that I should do. I only dip my corals, I don’t QT fish because they come from a very reliable fish store and I’m close mates with the employees there so if anything went wrong they’d be able to help me but all the fish there are pre-quarantined. I’m currently making water for a 50% water change because my NO3 is quite high most likely because I’d ran out of mechanical filtration for a bit so the sediment sat in the sump (which I have now fixed and run a filter sock and siphoned out the sediment). I know this sounds very bad on my end but I have heaps going on with this tank as I’m trying to focus on stability so I’m doing a lot to it and I’m almost certain my nitrates are causing this for the scopas. My parameters will be attached below (they aren’t the best because as I said I’m working very hard on stability).
