Sounds like you've got it under control for now, Oscarbreeder....because
of some good filtration and their "junior" size.
Your comment made me realize that no-one asked rallycat what sizes of Oscars
were being considered or planned for the 46Bow tank???
It always raises some eyebrows when I comment that such tanks can be used
(carefully!!!) as a "grow-out" tank for fish that eventually get larger.
That said, it can easily become a "nightmare" of tank maintenance and
related problems, if not careful, however.
I have many customers who "like simply to grow fish up" and then bring
them in to "trade" with. It would certainly be advisable for anyone contemplating
doing that, to make sure they have an "outlet store or ??" that will accept such
larger fish IN ADVANCE!!!
P.S. For rallycat, plants will simply be "toys" for Oscars!! Some have been
able to keep plants with Oscars if "nailed down securely"!!
