Hi everyone, I purchased a betta last Friday. I had him in the lily vase set up and quickly realized that this wasn't right for my little friend. I went to Walmart and purchased him a 5 gallon tank. It is a sort of a half hexagon shape, with a flat back. It looks really nice (well for a beginner like me anyway) and I thought he'd be pleased with it too. It is a mansion compared to the vase. The problem is that the filter creates a current in the tank that is too strong for him. It pushes him down and he can barely cross the tank. It is an Aqua-Tech power filter model 5/15. Is there anything I can do to correct this situation? I really want to have a filter because I found the vase set up was dirty every day and I would like to try some clean living for him. Thanks in advance!
