Idea on blenny for a 40g

[coelacanth]

I want to put a blenny in my tank, but I don't which direction to go with on which one, but I do know I don't want to do a lawnmower blenny since I have a pinkspotted watchmen and I don't want them to but heads due to similar shape and color. I know it isn't a guarantee that would happen but still.

I don't see a problem with a lawnmower and the pink spotted watchman.

Idk its not like a huge tank and they are both territorial and look similar in color and shape, but like I know it's more likely that they won't have much issues but it is more just on the off chance they do I don't want to go through the struggle of taking one out.

Lawnmower would be fine with the goby. Ive only ever seen blennies be aggressive with other blennies. Starry blenny is a cool fish too, so is a tail spot!

What about a bicolor or Midas blenny?

I have all three... Not in the same tank... I would say the lawnmower is the most Madonna, always Vogue'n and posing. The Starry is more lets play a game of 'Hide and Seek' and likes to hide in plain sight. The tailspot is new and is shy when I am around but from a distance makes her way around the tank.

Yeah lawnmowers are aggressive as heck with other blennies I noticed. Ive kept a few different ones and they were all like that!

In my 40 I have a tail spot blenny and flametail blenny, mixed in with other gobies, everyone behaves, I've never had an issue. But my tank is full of rock and hiding spaces, this is important for gobies and blennies.
