I find spider plants too aggressively growing to use in an HOB. If they get into the filter they completely engulf the cartridges with roots, meaning that you could not change the filter without tossing the plant. Spider plant roots are very aggressive and grab onto those things really, really well and grow right inside them. Eventually they clog the impeller and stop it completely.

In recap, I recommend spider plants only in open water where excessive root growth is easily removed or can grow without causing problems. although even here they grab a hold of anything they touch - gravel, driftwood, etc.
