I just tried to feed a blood worm to my new betta this morning, and he wants nothing to do with it. I eventually took it out and carefully placed a few floating pellets in a corner, and he quickly devoured them all.
I'm no expert, but I believe you can identify stress through discoloration, heavy breathing and strange "depressed" behavior.
Ah, well he's not having heavy breathing, discoloration, or strange behavior. He explores his tank and then comes over to see me when I go up to his tank. :]
