They can get to be a 12+ inch fish, saying that i'v never seen one bigger than the one I have at the moment, he's 7 - 8'ish inches (at a guess i'm no good with size's)
They are a slow grower, i'v not had mine 4 long but it feels like he's shrinking.
Same with most Cic there are "The good, The bad & The ugly" just a case of getting and seeing what he is like, well unless you get one from some-one you no that will tell you what he is really like.
I have 2 right now (will only be one in half of an hour)
i think i got "The bad"
this fish has a nast side, well he's not that bad as long as the other fish stay out of his 95%of the tank
hear he is be 4 getting his ass poundid by a 12 - 14inch walking cat (the GT was the 1 whom started the fights)
and hear he is after a fight with the Clarius
he would not think twice to go head to head with thig guy, look at the size diffrence
The second GT i have i think is "The good & The ugly"
he will let an Oscar half his size chase him all around the tank with out chalanging him, thats the reasion he is going in a min, i have had to split him up from the other fish as they all chase and pick on him
(hes the 1st fish)
what tank mates are you going/plan to put with him?
