I'll try it. I had a nice easy one like that years ago and when I got this new guy, I thought they would all be like that. Now I feel lost but I know I can entice him (or her) if I follow your suggestion. I'm having a brown algae attack in my tank right now though and may post about it to see what I'm doing wrong (I don't feel like I'm overfeeding!). So, on second thought, maybe I will pull him out until I figure out what I'm doing wrong overall. Thanks for the advice.
