They are 3 weeks I guess *they seem like they are SOO much older!!*

They are in a 10 gallon still, they have not ever had a water change, but water has been siphoned in from the 55 community so that its already cycled, with a little fresh water mixed in..

some of them are getting huge! and I wanted to move them to grow out in the 29 gallon with the croakers and 4 young platys .. or i might move the croakers into the 55 with the 9 juvenile bettas...what should I do??

should i wait?
should i move the bigger ones?
ahhh!
