Picky Marine Betta

[VO6]

Hey everyone I just purchased a new marine betta today, and he was eating frozen mysis at my LFS.
I tried to feed him mysis a few hours ago and he completely ignored it. The fish is currently in quarantine
right now. Mine might just be stressed from the transfer still, so I will try again tomorrow.
If any marine betta owners want to chime in, how did you guys get yours to eat?

When i got mine, he ate frozen at the store. Brought him home, he wouldn't eat it. A week in, i tried live ghost, he went right for it. I kept attempting frozen from time to time, using different methods but nothing worked. Again, a week since last feeding, I put in live ghosties and he ignored em. I've tried shrimp, mysis, blood worms, krill (both frozen and dry).
Eventually I put him in the main tank and a few days later, he showed interest in LRS Reef Frenzy. He ate it, just had to drop it near his cave and go away so he couldn't see me. (They are pretty hardy fish btw)
A week or two pass with doing this, now he will eat it as soon as I drop some around him as he swims around dusk. He wont eat silvers, tastes them and spits it out but easily eats the LRS.

EDIT: I'm not sure if he wasn't comfortable in the QT, he had PVC fittings to hide in, but nothing was dark in the tank, white bottom, white PVC. Just figured he will be better off in a tank and it seemed to do the trick.

Marine bettas can be difficult to eating dead foods. Although eating dead food at the lfs, when moved there is many times a reset. It may even happen again when you move him to the dt. Try some live ghost shrimp, even live black worms to get him settled in. These guys will generally come around given time.

Mine only ignores the smaller mysis foods. He likes the chunky mysis ( Piscine PE Mysis )

Ghost shrimp are great.
If they won't eat those for some reason, you can try feeder guppies even though they aren't of optimal nutrition for saltwater fish.

Good news everyone, my marine betta (not sure in the name just yet) is now eating frozen mysis. It might’ve already been and I just maybe hadn’t noticed. BUT it comes out of hiding to eat. I’m so relieved!
