Sand sifting fish/cichlid recommendations

[SaltyPlum]

Any suggestions on a sand sifting fish/cichlid that could go in a tank with a dovii and Peacock bass? I want a fish that will keep turning over my sand to keep it healthy. Both my fish are currntly 3-4" and would like get some sought of sand sifter now why the fish are only young juvies.

Geophagus cichlids. Only drawback will be when the Dovi, and Peacock get too agressive.

Do research on the largest geo species.
