Hello, just a question about a way to keep tubifex worms from creating a mess. I feed my fish freeze-dried tubifex worms a couple of times a week, but have noticed the mess they make inside of my canister filter. Does anyone have experience with this, and a way to remedy this from happening. I press them on the glass near the bottom, but it gets attacked by all the fish and starts to float all over the place until some of them ultimately get sucked into the filter.
