Enjoying Cichlids has a picture of a homemade egg tumbler in it that boasts close to 100% hatch rate of viable fry.
Great all around book as well.

I replied, but hit reply instead of reply group. So obviously the email sent to didn't get to you.
But hey, it was late and I'm a little addle minded. Here's the first response I attempted to post.

A tumbler is a device that simulates turning over the eggs as they would be
in a mouthbrooders mouth. Infertile eggs are lighter and generally rise up
to the top with the turbulence, while fertilized eggs gently roll around on
the bottom until they are developed enough to be moved to a fry tank. If you
strip a mouthbrooder and tumble the eggs, there's no worries about the
female (or male) being mal-nourished or eating the eggs. There's also no
worries about the eggs being spit early or held to long.

Well, if no one replied, I'll try.
Tumblers are a device used to incubate the eggs of mouthbrooders such as
cichlids and catfish. A gentle stream of water rises through the egg
holding compartment, just enough to gently rock the eggs and occasionally
roll them over.
This action helps the fry develop better, in an environment similar to the
parent's mouth where water is constantly flushed over the eggs as the fish
breathes.
A very simple one could be a net suspended close to an airstone or near a
filter's outflow. In a net, however, the fry can be scraped by the net or
picked on by other tank inhabitants.
While I have no need for this type of artificial rearing (I don't keep Rift
Lake fish), I have seen them in use at the Wet Thumb Aquatics hatchery. Good
hatch rates, females are ready to spawn again sooner, no predation. They
would keep a number of the tumblers in a 10(?) gallon aquarium.
HTH.

Great.. are they commonly used by hobbyist breeders or by larger
wholesalers/breeders?

neat idea, in a tumbler do the eggs just sit, I mean, what do they rest
against? because you mention the net could scrape them, how would you avoid
that???

The tumbler is made of plastic/acrylic, so there are no rough edges. The
water flow from the bottom keeps them semi-suspended so they don't really
bash into the walls. The eggs are usually fairly tough, but they can be
damaged.

Hi Jim

Out of curiosity, why don't you keep Rift Lake Fish. Is your water too soft?

I have only kept about 15 or so species through a full life cycle (growth,
mating, eggs/fry, growth). I just haven't found their "slam bam thankee
ma'am" approach to spawning all that fascinating. I am a much bigger fan of
New World cichlids and the non-Rift Lake cichlids.
I did install a full house water softener/chlorine remover a couple years
ago, but I can bypass it to get our fairly hard tapwater with the flip of a
switch.
I guess I change fish preferences occasionally (killis, Betta's,
livebearers, etc.) but I have enough tanks to maintain a wide range of
species with an interest in trying to spawn new to the hobby oddball fish.
Right now, the main emphasis seems to be on show quality guppies, which are
probably more work than most of the normally available fish.
Perhaps it boils down that I was too set in my ways when the Rift Lake
cichlid explosion took place. ;-)

Tumbler is a device that simulated over eggs, as they in mouth brooders mouth. Infertile eggs light, generally stand up the top and turbulence, and surrounded by gently rolling eggs their bottom until the development of the fish tank can be moved to.
