Around here, there are two kinds of females in the pet stores: crowntails and unidentified. I think that the crowntails are more expensive simply because you DO know what you're getting, they're easily identifiable.
I have another female, I suspect a VT, who is over twice the size of the CT.
I've never really been all that interested in CTs, honestly, so I've never compared them to other types.
I was simply wondering how much I needed to worry about her, is all.
If it's fairly common, I'm just gonna treat her like she's normal.
