Shark/Ray tabs are a yellow pill. They also make shark/ray gel diet which comes in a power - you mix it with hotwater and create a 'cake' for them to eat. It's a great way to get them the right mix of nutrients.
thanks for the info guys. i might try both and see which works the best i would think the gel since my guy seems to pretty much stick to pe mysis and some squid so he might get a little picky with pills . thanks again
