thanks for the reply Dorothy.
Yours does look a lot like mine, except that where yours is pink/white mine is more pinkyred/yellow but that could easily be from the camera as you said. I'll be interested to see if it is just young and will grow a lot bigger or if it stays small. I'm kinda hoping it'll stay small, it looks so cute next to my 2 big phals.
I'm going to google Phal Tai Pei Gold and Cassandra hybrids and see if I can find something that's 100% bang on to mine but it's great to have narrowed the field.
Thanks for the help
