I just purchased a 2" I think male green terror, he has a very pronounced head hump. I didn't think they get them this early, does it mean he will be large? I picked him from a tank raised selection of about 20 other terrors for $3.00. He is being kept for now in a 40 g. high with a small 3" I believe to be female black belt cichlid with no problems thus far. I have one aquaclear 70 and lots of rockwork for hiding. I've seen the other threads on growth rates, but I was wondering would a big head hump now, mean a large terror later? or does it not matter? thanx-salty
