I have a problem with my tiger barbs getting stuck behind my inwater filter system.:headshake2: I loved the filter when I first got it, its really easy and quiet. But now I have lost 2 of my tiger barbs to the filter. They get stuck between the filter and the glass. Is there a sponge that I can stick there to block it? And also, I now only have 4 left. If I get more they will be significantly smaller than the ones that I have now. Would the little ones be ok to put with my bigger barbs?
