This argument has been going around for a while now and most of the debates come down to stability. body shapes, color ect vary for each specimen, but the stability does seem to be a minor factor in discernment

I've kept alot of indo dats and they look quite stable when they are comfortable in an aquarium. Only commenting on this because I'm seeing these "Sumatra clean 4 bars" just now for sale for $120 when you can get an indo the same size for like $20. Most of the indos I've kept are awesome if you give them the proper setup and a little while to settle. I've also seen a bunch of indos with cool patterns.

do they color up once comfortable?

Mine seems to color up when, changing water, feeding time and chasing each other..

Very tough to distinguish these two species. Similar to that of Florida vs spotted gars. If you really want to know, send me a scale from the sample in question and a scale from a known sample. I’ll have a friend of mine doing their PhD in the biology lab to do a genetics test. Hooefully it determines something for ya. Stability can’t be used as a determining factor. Neither can color/pattern as all of these vary greatly between specimens.

Maybe these are not even two distinct species. Could be a clinal species caused by minor geographic isolation.
