i bought this eel as “African spiny eel”. It’s 7in long currently. I had some say it’s a half banded eel, but the eel is really long and its body shaped looks like the starry night eel I have in a separate tank.
For that price at the shown size you can decently say that it is not from the great rift lakes.
I would still go with loennbergii or frenatus. Or maybe one of the species that sometimes comes as a bycatch.
