None of this is answering my question. It's not that the goby is eating brine shrimp and it's failing to meet his nutritional needs, it's that he doesn't seem to want to eat anything (be it brine shrimp, mysis shrimp, or flakes). So far, other than picking on brine shrimp (and I seriously doubt any of you are really qualified to speak to the nutritional value of brine shrimp) no one has offered any useful advice.
It is said that newly hatched brine shrimp, with the yolk sak not yet depleted, have significant nutritional value. Once the yolk is "consumed" by the hatchling, well pardon me, but it might be similar to trying to eat a seahorse ( :scared: ) or a spare-rib (yuk!). Mostly skeleton. You would have to eat a herd of seahorses or a rack of spare-ribs!
No marine biologist here, by any stretch.
The goby family are carnivores. They crave and hunt for protein. The brine shrimp will not satisfy the fish, IMHO. As stated, because of size, try the cyclopeeze and any other meaty (tiny bits of silverside?) food you can find.
The brine, in the mean time, and if the fish will eat it, is better than nothing.
