You will love him. I used to have one in my folwr untill my ich epidemic. I was going to put one in my reef since i love fish that fill a need in my tank ( ive found these are best at controlling algae) but decided against it b/c i dont want a heavy bio-load. Dont be scared of the spines at first i was but then always developed a eye to see where he was at. Once they get used to you they will come up to you while your doing things in the tank. If you dont like it, buy some aqua gloves to protect you from the spines
