Yeah there weren't many openings to start with, just one for my lucky bamboo and another for the filter, so i placed socks to stuff the openings without blocking the filter and plant. I went to both petland and petsmart and neither had aquarium sand surprisingly so I'm still searching for some. I placed some pvc pipes and embedded them partially in the gravel to create caves along with just some more rock formations and dens for the eel to choose.
Heres a video of it eating which I somehow got on camera
It's doing well, most of the fish ignore it except the damn weather loaches think its another loach lol and keep following it and hiding with it and it clearly is ignoring them. Their spacial awareness sucks as they just cram themselves in with the eel and the eel's just peeved and has to leave because the loaches are massive and take up space. They are 4-6 inches.
