... with a lot of luck . I still don't know why I found Wiley at the front of the tank one night. I would look for him nightly without a spotting and then he was just sitting out in the open one night and I had a net handy (on purpose but I had give him up for dead for weeks, at least twice). I had not been feeding the tank and perhaps he ran out of food in the rocks but I can't be of help there. You might try putting a cluster of barnacles or a small conch shell at the front of the tank to see if he finds it to his liking. Putting a fiddler in something clear and easily accessable might tell you that he is alive. Neither worked with Wiley, however.
