My 6 year old Max....

Theyre pretty rizilliant for the most part, just watch out for Pyramid snails and preditors like the rabbitfish, some blennies will pick at the mantle, bristleworms can irritate the base or the foot but will not harm it, in general, with the proper lighting and acceptable parameters, you shouldnt have a problem. Good lord! Sorry for the giant pic! Can someone resize it for me??
