Tank Parameters 2 days ago when I noticed issues and first I double checked
Salifert kits
78 degrees
1.025 salinity
Amonia 0
Nitirte 0
Nitrite close enough to 0. The SLIGHTEST hue, not even readable
8.1 PH
1400 mag
460 calc
7.7 ALK (more on that in a second)
0 Phosphates
System is 3 months old. (set up for almost 6) 330 total water gallons. 220 display tank, 70G sump and 40G frag tank with about 40ft return and drain 1.5" lines. Currently in that frag tank (connected to full system) are the 2 clowns, 4 lyrtail anthias, 1 solar fairy wrass, and about 15 frags as well 1 larger zoanthid colony.
Clowns have been in there about 2.5 months, Added solar fairy wrasse about 6 weeks ago, and anthias just under a month ago.
All were in QT before they went into display.2-3 weeks. NOW, I did have an issue. The wrasse and anthias were bought about 1 week apart and there were 7 anthias at first. Caught up in every other parameter and practice I've been reading for the main system I lost sight for the most part of the QT and how much quicker things change. I noticed higher nitrites and did a 50% water change. Just assumed it would correct. Clearly it didn't. within a day all fish but maybe 2 anthias were not looking good. fins a mess, 2 of them about to die. I decided to move them to the frag tank (again in line with rest of system). The next morning the 2 I figured were too far god passed on. 2 days later another one did. The wrasse was faded in colour, a little more lethargic, but within a week their fins have all grown back, don't look frayed anymore and the wrasse is back to acting like a weirdo and looking great again. On the 10th I added 15 frags to go with my larger zoanthid colony. All looked perfect till the other day and this 1 clown.
As for breathing, yes I would say a little more rapid breathing, but nothing that looks like hes massively struggling to breath. Eating just fine, but staying a little more localized to a piece of PVC than normal, although for most part spent more time there in general, for sure now more so.
The night before I did change my gfo and carbon as it had been several months since. I also added 15ml ALK, as for some off reason even though I'm using RED Sea Coral pro salt with an ALK of like 12, my tank readings I've been raising from 6.8 to where they are now.
I've tried to do reading on some disease possibilities, but there is no slime, no black dots, and other than that, reading for this stuff is like looking up your own symptoms on WebMD so i'm trying to not make assumptions casue like everyone knows, if you look up issues you might be having yourself, you for sure have Cancer.
