They're also a little more aggressive than the Valentini's and like to pick off the LR.
I saw a full-grown one in our favorite LFS; he was about four or five inches and quite fat. I know fish don't usually grow exceptionally fast, but I wouldn't put any puffer in a small tank (less than 30 gallons), regardless of size. They love to roam and easily become restless.
More info to come!
