OK, here is the deal. I found a 5" female Dovii at a LFS for $25, first of all...is that a good deal? second, I have a 300 gallon tank with a silver arowana (11") an albino channel cat (10") a pictus (7") and a red oscar (10") am i asking for trouble if i introduce a Dovii into my tank? will there be enough room for all of the fish, and if not what would you recomend putting in that naked looking water box
?
