The Oscar is a she --she's 4 almost 5. Her egg tube keeps dropping, and when it does that rock gets a beating. She dropped eggs about a year ago when I had another Oscar in there with her...nothing came of it, and I re-homed the other Oscar. Jag is female--hoping she gets along with everyone..so far so good ---The Geo's I'm hoping for a pair. Still a young tank...as you all know things change in a blink of an eye with cichlids lol
