No. Marine Betta's (aka, preferred name of Comets) are in the family Plesiopidae. Not directly related to groupers at all. A tang or wrasse, would be equally related to a grouper as a Comet. They are usually the only species you'll see in the hobby of that family, other then occasionally Blue Devils (Paraplesiops poweri).
Yea, sometimes they are finicky to get eating, and only take ghost shrimp for a bit. Their peacefulness is their downfall, aggressive or bothersome tankmates should be avoided. They are quite cryptic and usually stick to their cave, only coming out during feeding. Small fish are typically fine, and ornamental shrimp, should be okay as well.
Thanks for the correction, i guess i just figured since they are always listed under the grouper section, thanks for making sure i learn something new everyday
