I sometimes see people say things like theirs are two years old and only 4-5 inches. Like I say, don't know what they're doing, but I've kept fronts a long time and always had the same results as above. Like most fish, occasionally an exceptional male grows faster or one might be smaller than average. Also, some people have different perspectives on 'slow growth', as though everything should grow like an Oscar.
After year one they slow down, usually after year three they slow down some more. By about year five they're usually close to as big as they'll get ime.
