My minibow has a whisper micro filter which doesn't have your typical intake tube. I need to put stocking over it to keep it from sucking up my fry but with this one, there is a small gap between the rubberband and the filter body and wouldn't you know one of the fry managed to find his way in there (but not back out of course-he needed my help for that). So I took off the stocking but since I plan to use this tank for fry again I want to get a filter that will fit in the tank and also has a regular intake tube that I can put a stocking over w/ a rubberband. Adjustable would be a big plus. Any ideas? It's a 2.5 gallon minibow.
