Have a tiger pistol. All he does is hide unless he’s
a) eating
b) defending the goby
But I’ve also only had him for two weeks, so maybe he’ll get bolder with time.
Voted other. I do not have a reef, but I do have a macro algae tank and a FOWLR. Currently in my macroalgae tank I have a coral banded shrimp, both for look and because they are supposed to eat bristle worms. Never saw her eat the worms, but it seems that I have less worms.
I used to have an harlequin shrimp also for look and utility. I returned it to the LFS when my asterina supplies dwindled down.
In my large tank, I had peppermint shrimps for a few years, but none now. I will probably get some soon as I do think they are fun. I got a cleaner shrimp once, but it only lived about 2 month. It was starting to come out more when it disappeared. I do not know if someone ate it.
I have a harlequin. I was worried it would be an expensive snack, because it was about 1/2 inch when I got it, and it totally disappeared in my tank. about 2 months later as I was cleaning the glass, there she was in all her glory, about 3 inches bigger!! she's beautiful, and has 3 caves that she stays in. growing like a weed, and I still have way too many starfish! love this thing though
