New tang dying

[Jake_the_reefer]

Update he passed away. Im very confident it was a parameters swing issue and he was a weak fish. He was very thin and could see every bone. My salinity is 1.028 and the lfs runs their tanks at 1.023 so I think it was just too much stress for the little guy

Sorry to hear -

Was the fish thin when you bought it, or did it become thin over the few days that you had it? A rise in salinity can cause a fish to dehydrate, and that will show as the fish becoming thin.

Still, as I said, acclimation issues are immediate and acute. For a fish to be acclimated to a tank and then feed well for two days and then develop problems are typically NOT a direct result of the acclimation.

That said, fish require healthy kidneys in order to balance the salt levels in their bodies - it is possible that this fish had some borderline kidney malfunction that then caused dehydration. Of, the fish could have just been in poor shape (too thin) when you acquired it and that caused its death.

We noticed he was thin on arrival from the store. We did think he was off right away because he didnt behave like any other tang we have ever owned. When added to the tank he didnt immediatley hide away he slowly swam away from the net and stayed out in the open.

0.005 jump upwards is a big one. Is there a reason is so high.

It would take several days to get him to 1.028 super safely, not that I would have fish in 1.028.

Should have been an issue right from the start though, so that piece, is confusing

Im mistaken i just recalibrated my refractometer. Im at 1.027 but in the past ive ran 1.028 on my sps heavy systems. Never had a big reason.

I mistakenly spiked my salinity from 35 to 43 the other week due to do trusting my apex reading instead of first validating against my tropic Marin hydrometer. All my tang fish did not appear to be affected by the rapid spike over night before I realized and corrected. The Starvation and weakness probably played a role with your case though. Are your running any power heads or protein skimmer. A properly sized skimmer and good flow are key to tang success imo. Outside of QTing first that is. I run a mid to high bioload rated reef octo on my setup.
