Seahorse Sam said they were 6 months old...the new male (Tony the pony, so named until my grandson goes home, I hate that name) is the size Fred was except Fred had a yellow tinge to his tummy, I guess after a certain age their growth slows down, Fred was a near a year old when he passed. The new female Daisy, is smaller than the other females by about an inch. I can't seem to get a picture with the old and new together. ... I'm working on it, once I get that picture I will post it.
