So i have a goldentail moray eel and i was wondering what he will be like when he gets bigger. so what made me have this question was me looking at him and realizing that he looks bigger than i remember and more agressive, even prettier. So i was wondering do eels tend to get brighter as they age? And i have already heard they get more aggressive. And how fast is a normal speed for them to grow? because this guy seems to be gettin big fast.
