i have quite a few monitors and my sav is very pissy and is not WC. i don’t think its CBB i believe it must be CH or something because when i got it it was sold as a hatch ling savannah monitor which it was. since then it quadrupled in size in less than a year. When it is an adult it will get its 8x9x6 cage. My recommendation would be Dumeril's monitor. they don’t get as big as sav but are defiantly bigger than ackies. They’re nice compared to other types of monitors but not nice compared to lizards in general.
