Hello all - I'm in the process of setting up a Fluval Spec III (2.5 gal) Walstad tank, using the filter section as a small non-lighted refugium for scuds, ostracods, etc. with dead leaves and twigs as the media. I thought it would be nice to try breeding a pair of Scarlet Badis with the refugium supplying food for the parents and babies. Has anyone tried a setup like this? Any success, suggestions,etc? I'd love to hear from you!
