What's the rule of thumb on keeping a baby (3 month old) leo in a tank with two adult leos (4 years old)? Right now, baby has own 10 gal tank and I was thinking I should wait until it is 1 year old before I mix them (assuming it's a she as the adults are 1 male and 1 female).
However, they seem to be okay looking at each other thru the glass and don't freak out like my Tokay did when he sees a leo close to him thru the glass.
Please advise.
