Otos in love and other sordid tales [OT]

Makes you grin, doesn't it? Love is in the air, uh...water, in one of my
planted tanks as well. I've got a heavily planted (i.e. out of control
jungle) 20H that is occupied by 2 otos and a half-dozen C.japonica. Well,
the otos are putting out fry like mad. Unfortunately, the fry seem to
disappear after a few weeks or so. They grow to about 5-6mm long and just
slowly fade away. I have two theories: They're either starving to death
(there is no visible mat algae anywhere in the tank) or the otos and/or
shrimp are snacking on them as they get big enough to notice. So, I'm
setting up a grow-out tank and I'll suck 'em up with the baster next time
and move them. I've given up on the "leave 'em alone" method -- three
known spawns in just over two months and no fry left to show for it :(
If anyone has any suggestions on the care and feeding of oto fry, I'd be
very grateful. I haven't found much useful info on oto husbandry so
far. I'm especially interested in foods for a maximum growth rate
(microworms, bbs, etc).
BTW, if you've never seen oto fry, you should. They are sickeningly
cute. When I find some more, I'll try to scrape up a decent camera and
post some pics on my website.
