marine bettas - how predatory are they?

[sparker]

I have researched it a bit and it seems these fish are likely to eat smaller fish. Could one of these eat a full grown ocellaris clown? Neon gobies would probably be dinner if kept with a betta, right? If anyone has some experience with these awsome looking fish and their eating habits I'd appreciate your input.

I have many in various tanks and have never seen nor heard of them eating smaller fish or shrimps. They're very shy and reclusive and rarely interact with other fishes.

My experience is different than Z2K. They eat like a grouper or bass with a hinged mouth that can take in nice sized chunks of food and small or long slender fish and shrimp. Very peaceful and slow moving, not aggressive to tankmates. If you have other aggressive fish in the tank they can pick on the comet or beat it to the food being offered. I had to find mine a new home because the other groupers I had made it hard to feed the comet.

sounds like you have 50/50 odds unless you're feeding dying freshwater fish...

They are really cool looking but I think I'm going to pass on including one in the tank I'm putting together. I would be upset if it managed to eat one of my clowns.
