Added a new rock to the tank. I thought I saw a very small shrimp during cleaning, but wasn't sure. Maybe the shrimp are breeding.

The angelfish fry at little over 3 weeks old. They're about the size of a pea. The father angelfish is looking on from the back in interest.
A closeup of he fry (busy pooping out digested brine shrimp). You can see the striping and coloring start to develop on the fish.

I noticed tonight that the male angelfish had some fungus looking growth on one of his side fins, he might be stressed out by all the mating activity. The pair been fighting a lot, and he's already cleaning out another leaf as if in preparation, even though they just laid eggs 3 days ago, and his papilla is showing. I added 25 mL Melafix to try to help with his fin.
In the tank picture above, you can see the two breeding cages holding the two sets of fry.
