What small combtooth in reef is "safe"

[JJIM]

Looking for a small comb tooth type of blenny for a 30 gallon reef.

Anyone have luck with any of the below?

1. Blue & Gold Blenny (Ecsenius lividanalis)

2. Horned Blenny (Hypsoblennius exstochilus)

3. Bicolor Blenny (Ecsenius bicolor)

4. Caribbean Sailfin Blenny (Emblemaria pandionis)

I currently have the Black Sailfin Blenny (Atrosalarias fuscus) and Tail Spot Blenny (Ecsenius stigmatura) in a 90 mixed reef, but very few SPS. Havn't noticed any real detrimental damage, but they do from time to time pass by and peck. I am quite certain they are eating film algae that may reside on the coral. I am looking for something other than the two I currently have, which i why I listed four that I am looking at.


Which is the best, or safest one from your experiences?

Bicolors will "sample" corals from time to time IME. I had one that used to nip at the stalks of my Duncans from time to time.

I just added a bicolor and have noticed this on the sps frag closest to his favorite hole
