They're getting big!   Above you can see Becko - the orange one with two black spots.  Also Aki - White with black spots and red spot on his head. On the far right is Lucy - the redhead. The bigger ones on the right are (from top) Spike, Hana and Momo.

You can see why Hana and Momo are the biggest fish.  This is them running up to us for feeding time.
