+1,While I don't support everything this guy is doing I will say that atleast he plans on getting a tank big enough for a full sized Sen. That being said however I am highly disappointed that he would even get this fish without having any other tank set up and waiting for it at all. Personally I've done almost this exact same thing, I'd buy a fish thinking I would have tank space later for it but that later just never came and I was always forced to re-home the fish at a later date. Honestly I think I would've been less upset about this vid if he had already had that spare tank he mentioned set up and waiting and all he was waiting on was the 75g instead of him trying to focus on another tank that is still far too small. Also it's not like Sen's are all that hard to come across, hell even chain stores sell em, so it's not like this would've been a situation of "get it now or get it never" so it's not like he couldn't have waited till he had a big enough tank first and then gotten the lil guy.
After being in these conditions it's more than likely this fish is stunted and why even bother with making a care guide of fish you barely know anything about.Judging by his other videos ,this was a impulse purchase probably saw it when he went to pet smart and bought it " oooh a dinosaur eel I have to get one!'' and kept it in this monstrosity of a tank.They're literally googling the name of the fish after they brought it home and what site calls a bichir a 'dragon palmas''
