Looks like a Yuma and not a bounce. The consistent coloration difference at the ends of each of the projections, and the orderly arrangement of them suggest Yuma, and are basically impossible to be bounce vesicles.
Hard to see what colors that ric is under all that blue.
Seen plenty of these around instead and picked one up awhile back. Under whites, next to a "rainbow" Florida.
That JB does look slightly different; it'll be interesting to see how it does over time. Momma JB, who's slowly getting her greens in, walked to the back of the tank where it's almost impossible to take a pic of her.
