adding blenny question! help

[jesse!]

hey I have a Lawnmower blenny in my 29g reef and I wanted to add a bicolor blenny. Would my LMB be agressive towards the bicolor. My LMB will probably be bigger than the bicolor because my LM is about 5".
all comments are much appreciated!

Yes. Two blennies with similar habitats in such a small tank is not a good idea. But at the same time, you shouldn't have a 5'' fish in a 29 gal biocube. You can have 5'' of fish, but not 5'' in one fish. I would personally take the lawnmower blenny back to the lfs and get the bicolor, even though I like lawnmowers better.
