Egg-laying pair of Clowns GVRD (price?? a little help?)

[Cujo#31]

Once I clear out my big tank, Im also going to move my mated pair of Percs. Like clockwork they lay a clutch of about 300 (?) eggs. They cycle about 3 weeks from clutch to clutch. Maybe a little help on pricing though, not sure what a solid egglaying pair is worth.
