Two Blennies

My Lawnmower Blenny keeps jumping into my overflow. I was thinking if I add another Blenny the first one might be less apt to jump out. Anyone have experience keeping two of these in one tank? My tank is 110 Gal.

 

Blennies jump. I've lost several to jumpism that ended up on the floor.

You'll need a physical barrier of some sort. I put a lid on my skimmer overflow that I made out of a zip loc 'tupperware' lid.

 

most blennies do best on their own (even the lawnmower) - adding one more just sounds like another problem all together. I would do what Peredhil suggested and you should be OK

 

Blennies are best kept single unless they are a mated pair. If your's keeps jumping into the overflow box, use some eggcrate on the top of the box to block him. You can also use mesh netting as well.

 

I am going to get some eggcrate tonight. I had a small piece that I put over the overflow last night. Only thing is I think the Blenny can squeeze through the overflow comb if he is determined and I do not want to block those.
