Mystery deaths

[WhitePanther93]

Have you ever had a fish that for some unknown reason just doesn’t make it?

a few days ago I purchased a lawnmower blenny. At the lfs he was seemingly healthy. He was monching ( the only way I can describe the way a Midas blenny bites is Monch)away at the rockwork in the tank. I took him home drip acclimated him and when released he was active, alert, and pecking at my rock work. Nobody was harassing him. ( was a little worried that my Midas blenny would)

but to my sadness after a couple of days I found his corpse sitting in the back corner of my tank.

anyone else have this kind of experience?

Was it quarantined at all? It’s possible you missed some sort of disease. Other than that, sometimes fish just don’t acclimate well to the new environment.
I’ve definitely had this happen in fw before, looks fine one day and the next it’s dead - though that seemed to be most common in the largely inbred fish.

I have had a mystery death in the past (Still unsolved to this day) with my Flashing Tilefish Hoplolatilus chlupatyi.

Here’s a part of a post I did on it a while ago (March 11th 22 after owning it since November 26th 22).

“I lost the tilefish today… No idea why but three-four days ago he jumped and never came out to eat. I tried to dig him out to get food in him but he was weak so I put him in a net, covered it with a towel and went out for a few minutes, came back home to check on him and he was unfortunately mouth wide open, not breathing and dead in the net.

I will be looking out for another one or two, but man I hate this. Even worse when you’re left with several ways he could’ve died but none of them adding up.”

It could be a Mantis Shrimp they kill fish

my thornback cowfish jumped out sometime last night, no idea why, he wasn't an easily startled fish.. I'm gonna miss him.

This thread is cursed. I just read this a few minutes prior and thought hmmm no I haven't, I've not lost a fish in several years. Just found my flame hawk that had been in observational QT for a month and eating well with 3 other fish suddenly dead with no symptoms prior. Then found a damsel in my DT dead. All the rest seem fine. The damsel was probably pretty old as I got it from another reefer fully grown a couple years ago. The flame hawk no idea.
