Marc Knight and collaborators published a study earlier this year in which some identification issues with these fishes were resolved. Specifically, B. canarensis was redescribed, B. malabaricus (which had been considered a synonym of B. canarensis) was revalidated, and a new species, B. ardens, was described. There are other differences, but they can all be told apart by colour pattern

In terms of fish in the hobby, B. ardens is what we've been calling B. canarensis. It has one row of vertically elongate blotches on the body, of which the first three are split into 2 smaller rows in large adults, and orange edges to the dorsal and anal fins:

B. canarensis actually has two rows of spots on the body and white edges to the dorsal and anal fins. It had been referred to as a form of B. bakeri previous to this study:

B. bakeri has a single row of spots on the body, and white edges to the dorsal and anal fins:

Finally, B. malabaricus has one or two rows of spots on the body and orange edges to the dorsal and anal fins. It has been referred to as B. bakeri 'orange fin' or B. canarensis in the hobby:

'Think' I've got these ids correct, but will ask Marc for a second opinion once the profiles are up. Also worthy to note that the spots on the body can also appear as vertically elongate blotches in B. bakeri, B. canarensis and B. malabaricus but they're generally much smaller than in B. ardens.
