Would I be able to keep 2 anubias coffeefolia in an unheated, unfiltered half gallon bowl? I've got eco-complete to put into the bowl and root tabs if need be. Would putting the bowl in a window help? They'll only be there until the 24th when I get my new tank, but I wanna make sure I'll have more than a rhizome with golden yellow leaves on it. Would this set-up be possible?
