Jillian,
Nice tank...but was there a need to start a new thread on this, after the thread on it yesterday, in the fish discussion?
This is a saltwater board, and while an OT freshwater topic comes up now and then, I think it best if a new thread is not started where an old one would be enough. Okie dokie?
Now, remember, freshwater tanks cycle too....don't go crazy adding a bunch of stuff to that. It is difficult to find an LFS that will take back big Oscars and other large south american cichlids. While it may seem empty now, it won't when those Oscars are 13" or so, and it certainly won't if they end up as a mated pair. Something you won't know for awhile.
