I believe I have an N wennerae that hitchhiked in on my Florida Keys live rock and I absolutely love this little thing. It has coexisted with 7 fish of various sizes with zero problems since May of last year. I've noticed more empty snail shells in this tank than my other tanks, but with an LFS 5 minutes away, I have not minded having to buy additional CUC for this tank lol. I hand feed him with tongs almost every day and he is not particularly shy or reclusive anymore, at least until about a week ago. He seems to have disappeared entirely. I don't see him at feeding times and I don't see his head poking out of any of his normal hiding holes. Is it unusual for a mantis to disappear for a time while they molt or something? I am definitely concerned as he was one of my favorite critters in the tank.
Only water quality issues were my alk and ca got a little low when I wasn't monitoring it as much as I should. Alk dropped to 5.4 and ca dropped to the mid 300s. Both are back up now after very slowly dosing a little extra. I haven't tested my nitrates and phosphates in a while so I can't provide that info at the moment. salinity 1.025.
