i disagree sorry mate,my jag ive had for 6months and hes grown from 2inches to 10inches already<thought that was quick>already up with the 2oscars who are 10inches and 1year old...that gt looks nice...yes cons if breeding will go crazy<ive ad exsperience in this
But did you raise it with larger more aggressive fish? I don't think you did, as oscars aren't what you might call aggressive seeing as my cousin's 5" jag always keeps his pair of 10" oscars penned up in a corner.
