It looks like you just about have things figured out, they're looking great. I used to Start feeding oto a around day 7 and off of rots by day 10. The tank stays a lot cleaner with out the rots. What are you using for rotifer feed/ green water? I was using rotigrow+ but ran out, I found RG complete locally but you have to use a lot more so I'm not a fan. I think I'm going to go back to the rotigrow.
