This photo is from a taiwanese fish atlas:

shows this guy as a "var." whats the diff between "var" and "sp"?

var. is like the same species but from different collection points, could have different coloration but is biologically the same fish. Sp. is a different fish, ex. different number of scales, skeletal structure etc.
