Figured I’d add some personal experience to this thread. I ordered three Phalacronotus bleekeri. Unfortunately they were bagged together and appeared to have mauled one another in the bag, so only one remains. I took the opportunity to preserve the two deceased fish and was able to view the vomerine bands used to distinguish the two species. I indeed appear to have P. bleekeri
Quite bummed about losing the others but I suppose that is just part of fish keeping. I would love to acquire some larger ones as these are proving to be a pain to grow out
