hmmm does your LPS sell live foods in frozen cubes? Cause I know my petsmart has small packs of frozen foods like brine shrimp for like $10...
:S I was just reading that you can't feed them just egg yolk, and once they get older, they might not be able to see the egg yolk particles anymore >.<;; man that would have been good information to know when I read about it the first time...
even though bbs can live for days, they have next to zero nutritional value after 8 or so hours. anyways, heres the email response i got from bettysplendens.com
Thanks for the email, I'm glad someone got some use out of the articles :).
I wouldn't worry unduly about only using newly hatched brine shrimp....some of the smallest may be lost in the first few days, but there is usually enough infusorians on hand to even keep the tiniest occupied until they can eat bbs, especially if you are using live plants in the tank. Seasoned sponge filters also attract infusorians, and there has been considerable evidence to suggest that the bubblenest itself attracts them.
Remember to use the newly hatched shrimp in the first 8 hours after they (the shrimp) have hatched. Their nutritional value plummets once they absorb their yolk sacs. When feeding them bbs, use a light source close by the fry tank. The bbs will be attracted to the light, and the fry will congregate there and feed. This makes cleanup very easy, since you only have to siphon one area instead of the whole tank.
Everything looks good, I'll bet you get some pretty CT babies :). Good luck,
