Okay well it's been about 4 days, if the fry haven't been eating the egg yolk they would've been dead by now. I'm kind of happy that they are eating, just I'm not happy I can't see them eat it... Lol
use a piece of tubing and just be really careful when siphoning out the water. i'd suggest rubber banding some fabric fine mesh (maybe pantyhose?) to the end of the tubing in the tank to help with avoiding 'fry tube rides'.
IMO, it is easier to get a turkey baster and suck the crumbles from the bottom when they're still young. After sucking it out, gently pour the water into a clear cup/bowl and check for fry (and remove them) before dumping the water.
Okay well all my fry apparently died... I don't have the time to start another batch so... I'm going to have a sorority tank with some other community fish! I'll be making another thread.
