2 new Green Mandarins died

Well I ordered online 2 Green Mandarins. They arrived appearing extremely malnourished. I put them in a quarantine tank with cycled water/media from my DT and clipped a piece of chaetomorpha from my DT's fuge to the glass
in the QT. There were already swarms of pods on the glass days before receiving the mandarins. Well I got them, immediately noticed their bony structure and sunken stomach.. Once acclimated one of them swam around but not much. Never attempted to hunt for pods and died 2-3 days later. The second one was on the hunt but it was too late. He passed a hour ago or so today.







The 3rd image gives a good view of the belly. Lesson is I will not buy dragonets online again (unless maybe WYSIWYG). They will be hand picked from a LFS before bringing home to QT/TTM. Its pretty clear lots of these dragonets are held way too long without a proper diet then have to go through the stress of shipping again.
 
I lost mine on Monday after being bought at my LFS on Saturday. Plenty of copepods and hiding places (only 6 other small fish in my tank too). He went through an hour drip acclimation too. He didn't seem too active and just hopped from rock to rock. I wish I knew what happened to mine too.

Most likely cyanide collected.

drip acclimation can be a killer, i would avoid it in the future, especially for sensitive fish like dragonets.
 
Which acclimation would you recommend for sensitive fish? Not sounding rude but interested...I know you can float the bag and add water to it but isn't that similar?

For most acclimations to QT/HT I just temperature acclimate and make sure to have the salinity of the tank match that of the water that the fish was shipped in.

I use the Reef Gently AccliMate and it has worked well for me in the past. I don't think it was the acclimation process in this circumstance. Also, the salinity was the same between the store and my tank (1.025).

The same acclimation I use for all fish. Sample the bag salinity with an insulin syringe, the match my QT to the bag. Float the bag (still closed) for 15 - 20 mins to temp match temps. Then cut them loose.

Easy peasy, and saves a lot of stress on the fish.
 
i keep QT at around 1.022.. usually shipping water has low salinity. I then add fresh water to match the bag salinity. toss the fish in right after

some mandarin just dont make it due to collection.. i bought a pair on bluezoo. super skinny. i put them in a 250gal and now they are all fat

I use the same method and have yet to lose a fish due to acclimation.
 
Do you then match the qt salinity to the DT for the transfer after the Quarenteen period?

Yes. I adjust it (usually up) slowly over the course of a few days.

My basement is usually fairly humid. That's where my qt is. So I will often just let the water evaporate slowly and not top it off. Sampling salinity once or twice a day to see how things are progressing. Then adjusting my water change water before adding or transferring.
