|One of our larval feeds at Pacific Planktonics is the 1st stage copepod nauplius of E. acutifrons, shown here under attack by a 4 day old longnose butterflyfish (lnbff) larva. That's about the largest food that this class of fish will eat at first. Other small foods work, but they are harder to provide to larvae dependably in large quantity.||
Clockwise, from left are yellow tang eggs, day 7, day 13 side view, day 13 top view. These fish hatched May 5, 2004.
Picture above by Les. Long dorsal spine and pelvic fins develop by day 10. Larvae are 1cm long at 35 days, and spines reach caudal peduncle.

|Here's the mystery fish again, 25 days old. Need another hint? Even though they were easy to feed, they all died by flying and getting stuck on the wall of my tank. Next time we'll use constant water spray to rinse them back into the water. Hawaiian name is malolo. Luis Magnasco says this is Hirundichtys spp.|
