Well, my McCoskers wrasse died after about 15 hours

My McCoskers wrasse died after about 15 hours. He was eating and swimming the night before and that morning. After I feed the fish, false percula clown, dimond watchman goby and the wrasse, he went missing. I found him last night dead. None of the fish seemed to be bothering him in any way. Tank is 75 gal with 30 gal sump/refuge.

I called my LFS to let them know because they refund at least half the money of the fish. But one of the people told me that flasher wrasses are hard to keep.

Any of you find this to be true?

I'd like to try one again.

 

Sorry to hear you lost him. Sometimes it just happens and we never find out why. While I can't honestly say about flashers, IMHO 15 hours is not "hard to keep", that's more like "there was something wrong with that fish", despite the fact he was eating.

 

Sorry for your loss Just curious, how did you acclimate him? Anything funky with your parameters?

 

I acclimated him for an hour with the, put a little water in his bag for an hour. That's how I always do it.. That's how I've always been told how to do it. My params are fine.

 

I would lean towards something was wrong with the fish or it was not acclimated to your water properly/slow enough.

 

What is your salinity vs. the LFS salinity. From what it sounds like to me, it could have been osmotic shock. You can lower salinity on a fish pretty rapidly and it still be safe but if the salinity rapidly rises, bad things happen. If your SG was substantially higher, 1 hour may not have been enough. I would ask the lfs if they run hyposalinity at all. Or was this in a reef setup at the store?

 

IMO Mccoskeri are very shy wrasses. If they see anything as a threat or any fish intimidates them they will hide and perish. 15hrs is a bit short and leads me to believe there was something wrong with him to begin with. I drip accli, but please rem this... as you slowly add water, you should be slowly taking out water. When you receive a fish the water is colder, the ph is low, and therefore the ammonia is not as toxic. When you add high ph from your tank into the shipped fish bag the ph will rise and the ammonia can reach toxic levels which can kill the fish. This is why I never accli a fish longer than an hour, but if needed I will do like you stated. Add some water slowly and take out some of the water letting it fill up again. Sounds like you did it right. Sadly sometimes, they just don't make it.
