i have a gerbilarium for my gerbils! lol and mine has a acage ontop! lol
no, long term i deffo wouldnt agree with. im my op, all cages should mimick the animals natural environment, and a tank dont do it for rats. but as a quick temp, like in shops when the rats go quickly, i would prefer to see them in a big aqaurium then those little slidy tank things that you see about 6 of them in.
