Just wanted to provide an update. The frags have expanded nicely and are behaving normally without showing any signs of infection from their cuts.
Here is a group shot of the three happy frags (along with my unfragged other elegance shown in the top right)
Here are images of each frag
The little tiny 4th frag is also doing well and shows some growth. I flipped him over so that his photosynthetic skin points upwards.
Do you think I should put the little guy in a antibiotic dip to ensure that he does not get any infection from his cut, or should I leave him alone?
