Hey Howdy , Don't know if it will help but ,when I raised thousands of freshwater angels , you could see if they were feeding by the pink colour of their little bellies ,which also extended noticably. Maybe the same thing would work with your little guys. Just a thought......................Dave
P,S. you could just syringe a few shrimp into the rearing tank and watch the bevaviour of the sea horses,again small angel fry can be seen attacking the shrimp .Using a magnifying glass helps . Good Luck
