Good luck, and congrats on your dedication to these fish. Tiny tanks and tiny fish with tiny fry and tiny mouths are, IMHO, far more labour intensive and challenging than just another big tank of cichlids. I admire the excellent care you've given these amazing little PITA's!Started a infusoria culture 3 days ago. The fry are too small to eat bbs.
With any luck you'll only need the infusoria for a few days or a week before they get large enough for baby brine.
