Picked him up earlier this evening. Magnificent is the only word I can use to describe him. Biggest GT I've ever seen. An EASY 8" will try and measure him later. Him and the 5" Oscar are getting on fine, Oscar knows his place. GT seems really peaceful at the moment. HOWEVER!...I do have a 1.5"-2" GT (I believe he is male, great colours even at this size, one in my avi actually) and he will not leave the large GT alone! Keeps having a good nip at his fin and shooting off, its quite funny to watch actually. Will probably have to re-home the small GT as I doubt my new one will tolerate that for very long! lol
I would remove the smaller GT as soon as possible. The large male GT is likely to "snap", especially if the smaller one is annoying him. You are likely to just have a dead small GT with no notice.
