What would be the best way to cover or baffle the inflow of an Aquarius Mini Might Power Filter?
I happened to glance at Rakki's tank today, and he was against the filter and flailing like he couldn't break free. I quickly unplugged the filter long enough for him to swim away from the inflow. His fins are looking fairly tattered, too, especially his tail. I don't think the current from the outflow is an issue for him because he seems to know how to stay out of it already and I've seen him play in it a few times, but the inflow appears to be a problem.
Does anyone have any temporary or permanent solutions I can try? I was going to check my local pet store for aquarium sponge on Monday, but if I can take care of this sooner, I'd be really grateful.
