for those who feeds market shrimp

[tan]

I used to feed the whole frozen market prawn with shell and tail on (but without the head), just drop into the tank. The ray just chew on the prawn to get the meat out then spit out the shell and the tail. It is messy, especially with shell and tails laying around within a couple days. So I just cut up the tail and drop the whole prawn with the shell on. My rays are about 12 to 13 " and they have no problem eating it. I just bought small market prawn. Sometime they swallow the whole prawn.

Try smaller pieces for the henlei. I've fed 4" hystrix and newborn motoro pups with really small pieces of shrimp. A trick I found was to use tiny pieces when first feeding shrimp (or any other meaty food) to my rays. Once they learn to eat the food, you can gradually increase the size.

I 2nd that

I would keep cutting it into 1/5 pieces till they grow larger...

In my experience, a ray chewing at shrimp and spitting it out hasn't yet decided it's definitely food. This is exactly what used to happen with my Hystrix when I was trying to get them to accept shrimp. One day the light goes off in their brain and they just eat it.

exactly what I was thinking. My rays always used to destroy shrimp and now they are starting to take it.
