I've had my betta for about 8 months in a one gallon bowl at work. He's been doing great. Growing and seems to be a happy betta. I just brought him home though. My husband likes him and wants to keep him home. So we bought a new home for the little guy. A 2.65 gal Marina 360 aquarium kit. It has a filter and lights. It's a very nice tank and the little guy seems to be adjusting. My concern though is when we feed him, the pellets get caught up in the current of the water flow before the betta sees it. I know that he won't eat the pellets if they stay in the water for any length of time, he seems to like them crunchy and fresh. When he was in the smaller bowl, I'd drop the pellets right in front of him, he'd just grab them, almost like he was eating out of my hand! Now the pellets sink to the bottom of the aquarium. He swims around trying to either find them or chases after them, but rarely gets them.
How do you deal with this problem, shut the filter off while feeding?
