that doesn't sound right. they are suppsed to be less harmful then a neon tetra. they are almost blind and eat micro food. are sure it was the goby, or could it be some odd death, or just a pleco kicking the bucket without any signs? how big is your goby? how big was it when you got it, if it eats that much, than it sould have grown a little bit? they are by nature schoolers, maybe u should get 2 or 3 more, and instead of it being mean to the others, and use its behavoir to declare itself leader opf the pack.
mine is 10" and is a loafer. his favorate foods are frozen shrimp (mysis, brine, ect.) i want to get a few more for him to school with, but the lfs want 15-20$. i thought i would watch at walmart, find a big one and quarentine it for a few weeks. i have owned 2 10 inchers at once, but they were slighty different species, and did not interact alot. i don't know if by "school" they mean the gobies will stroll arond the tank together, or if they will be lazy in clumps.
