Can you see what I see?

Sophie came home from school and discovered 4 tiny baby fish in the tank. We didn't know we had a pregnant fish! I tried to catch them but they are about 3mm long and move fast! (a clue is they are the sliver out of focus blobs in the middle of the picture!) Whilst Sophie was at tap Mark dashed into the pet shop and they are now in a little net so the big fish don't eat them.
Sadly we said goodbye to Frances, Katja and Alexia today but the baby fish were a good distraction.
I hope they survive but I fear they are up against it because I haven't a clue what I am doing!
