Thanks all!
I could not resist these beautiful colorful ponies. They appear to be adjusting very well and so far have not changed color. The orange one went straight to the food dish--from the bag! I guess she knew what she was doing
They aren't quite as personable as Suzy yet, but we are very happy with them.
The yellow hitch I found in Big Als and the orange is a Decoral "octopus coral" that a member on seahorse.org was nice enough to let me buy from them. The orange coral is their "home base" and they sleep there.
As to the Tigertails they were
super cute but after reading about all the possible issues I might have with them (and mixing species) I decided to just go with the Kudas.
