Thank you, it was years ago, I just never replaced them after that. I did love watching them feed though, it's really cool. The Electric Blue Legged Hermits are a newer addition, but I have heard people having problems keeping them, from what I hear they don't ship very well and sadly a lot die shortly after the collection/sales process. Mine seem to be very happy, I just have to keep them that way, lol. Your tank seems to be coming along quite nicely.
