Does anyone on here have any experience keeping seabiscuit's if so please chime in I have a fairly big one about 5 to 6 inch in diameter and about 3 in thick just curious on if I can put this in a tank with Triggerfish and puffer fish or if they will try to flip it eat it or dig it up and eat it I've looked everywhere and can find no information on this I do know that it is a type of sea urchin and usually puffers and triggers will eat these sorts of things any info on this would help thank you very much
