But as with any similar confusion, it can be slow to gain widespread acceptance as many will still use outdated reference material like the Aquarium Atlas or something.
If you check the photos in our profiles, you will note that the "candy cane" is nearly identical to H. rosaceus in the fin white markings, something which is completely absent in the true H. bentosi. But whether this is a distinct species, or just a variant developed by selective breeding, I can't say; I have never found anything specific on this.
Thanks for the info Byron, and I agree. When comparing pictures of the fish these guys look very similar to H. rosaceus expect for the difference in the markings on the dorsal fin. Have also observed this morning these guys and my rummy noses doing a bit of that tetra sparring. Have before now observed them swimming together and at times the groups intermingling. After reading through the profile again I see that this is common behavior with the different species from the rosy terra clade. From what I have seen there doesn't seem to be much info on these guys. Will be interesting a time goes on if any more information is published about then.
