This is specifically on the species pangio anguillaris (eel kuhli loach), pangio cf. anguillaris (brown eel loach) and pangio doriae (golden eel loach). I hope it helps people! Personally I have been frustrated due to buying these eel loach species under the wrong name (p. doriae among p. oblonga schools, p. doriae as p. anguillaris, p. anguillaris as p. doriae and p. cf. anguillaris as p. anguillaris) so I want to help shed light on these hard to identify loaches. Since I'm only a hobbyist, if I got any information wrong, please let me know!
