Trigonostigma espei

As always, I see the work of some expert fish photographers here.
T.espei are often sold as T. heteromorpha in the States. The majority of hobbyists are only casual fish keepers and are OK with the mistaken ID's but as a more knowledgeable fish keeper, what I often have experienced is that when I am looking for T. espei the shops have T. heteromorpha and T. espei when I am not in the market! I prefer T. espei but both of the two species are beautiful. I just prefer the more slender and orange T. espei the prettier of the two, personally.

I agree. Much nicer when kept in large number.

T. espei has two populations from southwestern and eastern Thailand, apparently with some coloration differences. I speculate these two drainages were once connected during the ice age which has now being separated by the Gulf of Siam.

Could you try to describe these differences?

It would be super if you could also depict it through images.
