Hello! I have a diamond goby and I am a bit worried as every time I feed him pellets, they just go right through his gills as he sifts the sand. He is only about 2-3 inches and the LFS showed me he ate pellets, but he won’t eat them now for some reason. I’ve ordered some Ocean Nutrition formula 2 as well as PE mysis pellets but I am unsure what else would be potentially effective. He has a small curve on his belly when looking at him from the side but he is generally healthy looking from top down and it doesn’t look like he’s starving, so I don’t know if he is actually taking bits of the pellets every sift or not as they are too small for me to tell.
