Friend of mine has a Beta in his tank for 10 years, pretty old fish
the fish is pushing 6 inches and for the size of the fish it really has a small mouth, I don't think it could eat a full grown Wrasse. Went to the LFS yesterday to pick up some feeder shrimp for the Beta, which I didn't get as he was out
he did sell me some fresh water guppies
I put them in the tank, the Clown Wrasse acted like he wanted to eat one but I never did see him eat one, I never saw the Beta get one either
He stays in the live rock and is kinda hard to see. I have been feeding an extra Myies shrimp cube along with a few dry pellets, trying to get plenty of food in the tank and hope the Beta gets something to eat but I haven't seen him get anything yet. Thats not to say he isn't, I just haven't seen it yet. The guppies are all gone so I hope he did.
