I have 2 RBTA that are for sale for $40 each !! Pm if your interested !!!
They are about the size of softball when open, it has long tentacles when extended out.
Most of my RBTA stay close to the edge on the rock so it's easier for me to just break the rock and this minimize the trauma on the nems!!! Lol I know, its weird that way !!!
1 sold , 1 pending but I was able to remove 1 more for which it's the mother RBTA that I'm been contemplating to let go but if anybody is interested, I can let it go for $60 and the mother had given me 6 nem babies for the past 1 1/2 years!!!
