Hello,
Can someone please advise as to whether a newly acquired half-banded eel (3.5 inches) can live in an acquarium with gravel, like this one:

I have read that they need sand. There are quite a bit of hiding places, etc. although today I found him (or her) hiding in the sponge filter... If they cannot live well in gravel, how to change the substrate?? I am afraid all of with work in getting the acquarium established will be gone if I change the soil. Moreover, I have no idea how to clean the acquarium with sand - wouldn't all the sand get sucked up with the debris? Otherwise the eel is eating and seems OK (after a week from the shop).
Many thanks!!
