Like someone else said, cyclopeze are freshwater and certainly not bioengineered. They do have lots of astaxanthin, which is perfect for oranges and reds. The freezed dried stuff is "ok" but once you've used the frozen you'll think it's worthless, it's that much better. You should wash the frozen stuff in a brine shrimp net though as it has a lot of waste that will just get in your tank. That waste IS a good source of pollution and as Scott pointed out, the start of velvet in many killifish keepers tanks. Let's not forget though that killifish people try to raise fry in 1 quart bowls :-) so their water quality can go bad much faster than someone raising fry in a 5 or 10 gallon tank. Bare tanks and snails and careful feeding is the way to go. You still need LIVE baby brine shrimp as they are smaller than the the frozen C-E. You can raise bows w/o but if you do the side by sides your fish will grow much slower w/o live BBS. Rainbowfish don't eat baby brine shrimp in the wild,
ditto for frozen BS but they do fine on it in our tanks. The young especially enjoy the frozen cyclops-eze when they are large enough to eat it. I usually put a squirt from an eyedropper in the tank of fry then go on feeding other small mouthed fishes, then come back to see if the fry need another squirt of food. That way more stays in the water column and I can guage what they need a little better.

Planted tanks - rainbowfish alone aren't going to inhibit algae. I have had tanks that have had hair algae problems and the bows haven't been much help at all. For my 7 footer, besides the rainbowfish I have some long-finned rosy barbs and also some gold barbs as they really do a number on filamentous algae. LF barbs are easy to catch if you ever want to remove them. Gold barbs are dumb enough that you can eventually catch them w/o destroying the tank. SAE's have also been added but I think I might avoid those in the future, unless I got an outbreak of black/brush algae. (that's NOT the blue-green stinky algae, nothing really eats that). SAE's aren't that helpful when they get big and they just add to the bioburden. Amano shrimp certainly help to groom the substrate and they are interesting. I have about 50 of them in this tank and they are very long-lived. BTW this is a real planted tank, not just a tank with a sword plant in it, which unfortunately is some people's def of
a planted tank. It has almost 600 watts of PC lighting with quality reflectors and a light amount of CO2. I can grow most of the plants available in the Aquatic Garden trade but there are some that require just a tad too much light/chemicals/CO2 that are still beyond this tank.
