TCzelis. your right the tail stripes are not a definate way to determine species. this picture is a very good example of this.
But Almost all the time when they are that different on either side it's an indo. Those together (tail stripes and body pattern.) are ussually easy ways to differentiate from IT and ST
... the one side does look like a widebar I'll give you that. but the other side is definate Indo. which is what leads me to believe thats it is an Indo dat.
...and no, pulcher, I'm not an expert, I have just learned over the years how to differentiate the different species of datnoides so I can help give the proper i.d.'s to people like you. So obviously your not much of an expert either so who are you to test me with your childish antics.
