Ok, that is a? an? UG or undergravel filter. (none / 0) (#9)

They are excellent as biological filters. If they aren't rigorously cleaned and the gunk taken out from under them, they should be torn down and restarted after a year. Otherwise dirty ones can be something of a biological time bomb and everything is at risk if the tank sours.

Other than that, they are perfectly safe for live bearers. A friend discovered that UG filters were not safe for his cave spawning cichlids. His Julidochromis spawned under inverted flower pots or the plate-like thing pit under pots. He must have had quite a current going, because when the Julies excavated the gravel out from under the plate and the fry hatched, they were snatched away under the filter plate!

Other filters (box and sponge) also are bubblers. :) Each has uses which may make them best in certain circumstances.

All the best!
