Introducing Younger Fish Into A Mature Tank?

[vanderdraay]

Hi everyone ive had some success breeding ellioti's and grown a few to about 1.5 inch, at what point would you introduce them or are they to small yet , ive got a few geophagus brasiliensis in that are around 5 inches and others of same size , would you grow them a little bigger before introducing or would it be ok now .any thoughts would be appreciated


many thanks
