My squammie grows faster than my giga also. Is it showing the white rims of growth? I have not had gigas in the past. This is my first. But I am guessing they are a bit slower growing. My squammies and derasas were much faster than my giga and certainly the giga is faster than any crocea or maxima I have owned. JME
