I've had my betta for over a week. He swims around but won't eat. I've tried the reg betta pellets then tiny baby ones and dried crushed baby shrimp. I think he's blind and can't smell. I drop it in same place he swims up to same area in the front of the tank I put it in front of his face it floats around and he ignorss.it. I've tried different times of the day and evening.
