I have a bi-color blenny in my 75g and I'd like to add a lawnmower as well. Will they get along? There are tons of nooks and caves.
 
I have always kept a combination of a Midas Blenny w a lawnmower, starry or black sailfin Blenny w no issues, but it may be because they have different niches. Hope that helps a bit.
 
No, and I would bet the lawnmower blenny would kill your bi-color blenny.

As Bernie21 suggested, you may be able to keep a Midas blenny with a combtooth blenny. Or you may be able to keep a fanged blenny with a lawnmower, but mixing two combtooth blennies will almost positively result in the death of one (unless you have a huge tank, even then...). IME, lawnmower blennies are one of the more aggressive blennies out there.
 
I've had a lawnmower blenny for a few months now. After I saw a friend had a bi-color and how silly it acted, I wanted one. It's been 2 weeks now in a 60 gallon tank with no problems. They swim right by each other and....nothing, they get along great!
 
I had an existing starry blenny and added a midas. Expected a little bit of scrapping but there was none at all and in fact they were happily mixing within minutes. I then had a tank crack and needed to add a tailspot from another system or lose it. Again no issue what so ever and never seen an ounce of aggression between any of them and the tank is only 190 litres. So it can be done but i still wouldn't recomend it.
 
I've kept Lawnmowers and Starry blennies together. And those are both Salarias species.

Blennies aren't really aggressive like that. They are very protective of their feeding grounds. Which means they'll chase another blenny away from their favorite spots, but they won't necessarily take it as far as killing the other fish. And eventually it develops into almost a form of play between the blennies.

They are strange that way. They actually seem to like having their own kind around. They just hate sharing. That is about at the edge of having enough space for both to co-exist. I wouldn't attempt it in a smaller tank then that though.



But if you want complete compatibility then do as Bernie suggested. The combtooth and fang blennies seem to ignore each other.
