My guppy fry are about seven weeks old now. I'm just wondering if they're ready to move on to their other homes now. They're at just under 1 inch but definitely no where near the size of the adult guppies yet. 6 will be moving in with a friend of my friends whose raised fish for a long time. Will they be ok to go with him now? I just don't want them to die as soon as he gets them. Should I wait a little longer? Thanks!
