i dont have the problem so much in the ray tank but i use a piece of 2' pvc tubing like whats used for water pluming one end is cut at a 45 degree angle and the other straight and its very hand for geting food to particular parts of the tank . straight to particular fish to get them the first choice or just to get the food past the flow and to the bottom befroe it disperses in the flow.
i used this to feed my knife fish up whilst it was in the tank with other very agressive feedts . also used for other fish too and a couple of times to make sure my recently deceased stingray was getting food .
feeding from both ends of the tank at once also helps .
and i hand feed my silver aro he bites me all the time but its not painfull . im suprised it hurst the rays so much but i know it does as ive had rays bitten by slivers in recent years.
