That's a very plausible cause, since the carpet elevates the substrate
reduction effect over the real substrate level. Have you considered more
bottom dwellers such as corys to mix things up? In this particular case
they might help wouldn't you say? Revolving the area and anihilating
that mid-aerobic layer....
