How big do pincushion urchins get? Every source I look at seems to have a different answer, some say 3'' others say 8'' one even said 12 :worried2: All the same species Lytechinus sp. So really how big do they get? and do you think one would work in a 38g 3 foot tank?
 
About the size of a pincushion, actually. A very large one could potentially have a body 5" across, but 3-4" is more likely.
You'll definitely have to feed it nori or veggies in that size tank.
