for the most part Tubs are beautiful and very blue...but i think you have to keep them in low light..the high light mine were under seemed to turn them purple...
when i bought them i was told they would get a bright yellow ring around them if put in high light...no yellow ring for me...just purple polyps with white mouths..
my experince with blue zoos tells me to keep them in low light...
