Well different corys take different amounts of time, if you look closely you can see albino fry in there which take 3 days ish to hatch and are about 1 day old
Pandas....
1st pic: Just laid about 12 hour old egg.
2nd pic: Black egg about 4 days old, should hatch today.
3rd pic: The ones with the rounder heads are roughly 3 days old, they eat first bites and every morning i add some liquifry to help add insofura to the java moss.
4th pic: 6-7 days old, they colour up fast and get the same shape as an adult panda cory, they still eat the same first bites and maybe some frozen cyclops.
5th pic: The left one is about 3 days old the right one about a week.
6th & 7th pic: They will be 4 weeks on Saturday. They get big fast but could get bigger if they were not in a tank with adults.
8th pic: Its a juve i bought about 2 months ago, its around 6 months old.
