Aw, so cute! I didn't start fozen foods till 2 months, but my first spawn has always been on the smaller side. I'm trying to 'power grow' this new spawn, feeding pretty much 4-6 x a day (I have 4 snails scavenging the tank)
I have a sponge filter going from the beginning. That way it is already cycled. I have it set to about a bubble a second in the beginning, from spawning. Then about once a week I increase the bubbles.
I don't fill my spawning tanks, so I introduce a gallon of water a day on a drip, after the first week. By the time they are 2 weeks, I start carefully doing water changes.
The first spawn, I used airline, rigid and flexible, and I sucked up many a fry. This time I'm putting pantyhose or something and just going to change water daily and not worry about all the crap on the bottom until they are much bigger. When it gets really dirty I'll take my little medicine dropper and remove some. Tedious, but I don't want to have to constantly worry about sucking up the babies.
