Housing 2 Midas blennies in one aquarium
 

Has anyone ever tried to house 2 midas blennies in a 29g biocube? will they fight?

two is too many for such a small tank. They can get pretty aggressive with others of the same species. stick to one unless you are getting into a tank over 100 gallons or with a large foot print.

IMO, most blennies prefer to be solitary in aquariums...

Thanks guys- this is exactly what I was thinking. I was readning at different forums that you can put mutiple blennies in the same tank, but based on my experinece with my one midas "peaceful" blenny who constantly fights, I don't think another one will be much appreciated!
