2 Blennys in the same tank?

[Nadiaa]

I have a Ecsenius stigmatura and would really like a Ecsenius midas as well. My tan is a 40 gallon with a lot of rocks and caves. Do you think they will fight or get along?

they may or may not - I'd add them at the same time to reduce the possibility of one "establishing territory" first. I would also have some sort of plan for removal of one if it comes to that...

I've got a tail spot and a flame tail in a 40 gallon, they leave each other alone. Once in a while they do the open mouth thing to each other, but thats it. They've been in the same tank for about 2 years now.
