You have some don't you? Mine haven't fed yet, can I ask what do you feed yours? And is it true that they're substrate sifters similar to Geo's?
Sorry, didn't see this part of the post! The mfk app is buggy sometimes.
Aside from the breeding pair, I have about 45 remaining from the 160+ fry that made it to the free swimming stage. About 115 were sold, donated to conservation programs/clubs. Also traded with ACA C.A.R.E.S. members. Dr Paul Loiselle also has about 10 of my juvies. Many of the NJAS members have groups from my pair's spawn. The pair laid about 500 eggs. They were spooked by my female Bleekeri and ate most of the eggs. I pulled the rock and hatched artificially.
Yes, they're sifters, as are most Malagasies. The pair is constantly moving sand out of the perimeter of their 'cave' where they spend most of their time. Interestingly, the juvies aren't sifting yet. Maybe it has something to do with sexual maturity, I'm not sure. My Bleekeri makes giant piles of sand, usually into the corner where the heater is located. My Menarambo leave small pits in the sand when they forage. My Maculatus don't do this at all yet, they're about 3.5 inches now.
My group of red head Tapajos, in my SA tank, seem more like sifter/spitters and make quite a mess. The Malagasies mess is more contained to their territory, while the geos just spit everywhere.
Regarding feeding... Others may have different experiences. With my fish, the paratilapia and ptychos seem to prefer eating at dusk and dawn. Or in the middle of the night. They never eat during the day and will stay hidden if the lights are too bright. My ptychos prefer shrimp pellets, NLS Cichlid pellets and veggie or bs flakes. They can be very picky and slow eaters. They dont rush to the top to eat and will sometimes wait till food falls to the bottom and sift around looking for food. If I kept non Madagascar fish in their tank they wouldn't get to eat at all. The lighting for my mad. cichlid tanks is always subdued, they are more active at night as well.
Hope this helps! Feel free to ask questions at anytime
