Hello everyone my name is Jon Crossan. I am new to this site but I've seen lots of good information circulating through it so I thought it would be a good idea to join. I am the proud owner of a little O. mercatoris and so far he has been doing great (not sure if its a he or she but I'm just assuming). His name is Charley. Before I had charley I owned a O. Bimaculoides that went into hiding, never came out and eventually died of reasons im still unsure of. Now charley is starting to do the same, but I do see him slightly out of his new little hole he hides in. I'm pretty positive he is eating healthy because hes been scarfing down all the fiddler crabs I put in his tank and seems to love them. Hes also been eating ghost shrimp and hermit crabs. I would just like some suggestions on how I could maybe stimulate him to come out of his hole more often so I could interact with him more. When I first got him I played with him and he didn't seem to mind at all, which was very surprising to me. But now hes gone into hiding and im not sure what to do and don't want a repeat of my last octo. Please help!
