I worry about the same thing, especially with the cories - they're a bit too curious for their own good LOL (hmmm curiosity killed the CORY cat ???). After the gravel vac part is done I'm thinking of putting a clean knee hi pantihose over the end of the python tube so that water can get in but not fish . Has anyone tried this ? does the pressure just suck the pantihose into the tube ?
