Hi I need help trying to figure out what species of spiny eel I have. I bought him a few months ago and the store owner thought it was a yellow tail. It accidentally came in with an order of kuhli loaches. It looks just like a yellow tail but the tail itself is not split into two sections like a yellow tail is supposed to be. It is currently 2 and a half inches long. This is driving me nuts. Any ideas would be great. Thanks!
