guys, last night i was reading on Dr Ross stingray guide book, and i read an article about Argulus Sp. (Fish Lice) and i see the pictures of the creature on the book are similar to what this ray (mine) has under its belly, little brown thing crustacean. The ray is eating greedily. Should i be worried of this Argulus? Or is it just a normal belly spots as you guys said? Thanks for the advice..
