Well, today the mom let me get a decent look at the little ones. She usually keeps them wrapped up tightly in the heaviest cover available. Being a 180g tank, it's pretty hard to see everywhere. Literally, I've seen them 4 or 5 times total since they became free-swimming. Today she had them packed in around the lower roots of some Blyxa japonica. They're amazingly adept at pecking around for food. Like their parents, they seem to be perfectly happy scavenging off of the lower levels of the tank. They are growing, which is reassuring. Getting food directly to them would be next to impossible in any case.
Dad is starting to take turns once in a while, even letting mom get some food at feeding time today. When I was able to get a good look, I could see that there are still 20 or maybe 25 of them.
The fact that the parents have kept them alive for this long blows me away. Their aquarium has a dozen full-grown congo tetras, over 30 rummynose, 15 cardinals, and some other odds & ends, not to mention two other pair of dwarf chiclids and one lone surviving ram.
