BSJ spitting out some kind of white eraser looking substance

[yaridong]

hello,

my BSJ will come out of his rock/burrow area and spit out some kind of eraser ball looking thing that is like a white grey color. it seems to be some kind of feces like substance as the shrimp will come over break it down and eat it....

i only feed the BSJ mysis shrimp. he seems to be pretty healthy. had him for about 2 months...

anyone know if this is normal or if its a sign of something bad to happen?


(i just saw my plate coral eat one of the eraser things he spit out... i think he spits this ball out everytime he eats...HMMMMM)

Is it a blue spot jaw fish ?

 

[yaridong]

BSJ will move sand in their mouths to build a burrow. Is that what he's doing?

 

[yaridong]

no it is not sand that he is spitting out. it is a round ball of digested food? im not sure what it is, but its edible...
