Since we last wrote at Day 50, we’ve observed a lot of interesting things with our yellow tang larvae. Probably the most important thing we observed is their very inefficient feeding capability. At their size (~1cm), newly hatched Artemia nauplii should have been easy prey, but time and time again we’d watch them strike and miss, or partially catch one only to spit it out. Artemia nauplii definitely don’t seem to be adequate to sustain yellow tang at this stage in development. Likewise enriched Artemia were all but rejected. Also, at this stage, the fish seem to rely on their large pectoral fins for propulsion and were very awkward moving around the tank. We would frequently observe them floundering about and then suddenly right themselves and swim on quite normally. This seemed to require a lot of energy, which in their compromised nutritional state, likely lead to some additional stress. They also tended to gravitate MORE:Yellow Tang… so close, yet so far… – Update from OI… More:
