Looking for ideas of a final fish to add.

I'm looking for a medium sized fish to add. Not too large, but bigger than 3 inches. The only requirements are that they wont a.) Eat my Macroalgae or b.) Eat my other little darlings. I do have a cleaner shrimp in there too that I'd rather not get eaten. If I get anything too small or docile my 6-line will probably dominate it's life for a while. Thanks for the input in advance.

 

How about a tang or rabbitfish?

Both would eat nearly any macroalgae, which he doesn't want to be eaten.

That requirement kinda has me stumped.

 

Yeah, I admit it makes things very difficult = / I wish I could throw a tang in there, but then my water quality would plummet after it plows through the macros causing more work for me. I like not having to change water as often as I did before macros = p I am stumped and was hoping someone could have an idea for me.

 

dwarf angel but they may or may not eat macros, just depends on the fish.

 

Hmm, I'd enjoy one but I don't know if I'd want to risk it. A flame or lemonpeel angel would look awesome in there.

 

A fairy wrasse, theres quite a few that are gorgeous and get around 5"

 

Would the 6-line eventually get used to them? I figured they'd fight. If not I've seen a lot of them I'd love to have.

 

Why not move the macros to the sump, and add a Tang?

 

6-line might kill it. I can think of a handful that get to the 5-6" mark, but they're a bit more expensive and I'm not sure how much you're willing to gamble with that 6-line.
