We have one really old newt living in a community tank with tetras and a pleco, we want to move him to his own small tank, we thought we'd just fill it about halfway with water, add a nice rock for him to lay on.
The tank would probably be a 2.5-5 gal, what would be the best filter for this tank and do we need to add any beneficial bacteria from the bigger tank?
I don't know much about amphibians, he is a really old and feeble newt that rarely moves, he swims very little and mostly just hangs out on the floating plant mats in the tank he is in now.
Thanks!


He'll do it a couple times then the frog will jump on a rock then it swims on it's merry way (looking rather pleased with himself I might add.) Anyway he's doing fine and adjusted to his new tank fairly quick, I think he was just lonely.
