In my tank it would be my Kole. Keeps the rocks clean, eats detritus and other fish poop before it hits the bottom and is a beautiful fish that is always active and curious.

We just got a kole tang a couple of months ago. Her color is starting to really look good. I agree with you a great fish!

I really like algae eaters. My starry blenny was really a cool little fish (well, he still is, but now he's in @hybridazn's tank). I'd add sand cleaners too like a diamond goby.

My Fox Face won't let algae grow and feeds my corals plenty of fish poop

Foxface are so beautiful

I have to agree with all above. I have had my Kole for almost 7 years and it is not only beautiful, but so helpful. I loved my fox face till he died of old age. Now I have a rabbit fish I hope can keep up with him. Lastly, love my lawnmower blenny. Such fun fish.

These are in a 210g. In a small tank, I am not sure what my fav would be. I have a lawnmower baby in my 40g. He is fun too.

I have a soft spot for blennies especially lawnmowers, bags of personality and don't stop eating. If I don't clean my glass for a couple of days it's covered in kiss marks from him grazing.
