In Nepal moringua paddletail eel lives in freshwater...its inland state...but often they are caught in river mouths in INDIA...I’d suggest checking ur water quality. Needs brackish water last time I checked.
i have eel two weeks.Other fishes with eel are: tire track eel, stone loach, crosocheilus loach and goldline knivefish...all fishes are small sizes or juveniles.all fishes are feeding with frozen bloodworms.How long have you had the eel? Most eels don't eat in the first day or even week.
I'd say give it a little more time, maybe put out the food at night in the dark with no lights on.i have eel two weeks.Other fishes with eel are: tire track eel, stone loach, crosocheilus loach and goldline knivefish...all fishes are small sizes or juveniles.all fishes are feeding with frozen bloodworms.
