I just got a deal from petsmart selling 1/2 inch salvini's for 2.29 each and picked up two of them they are in a 90 gallon with a divider between them and the big guys. However the dominant one is small enough to slip through the side of the divider and is quick to avoid the big guys and eventually goes back to his side of the tank into his cave. The only concern is the less dominant salvini is being harrassed by the dominant one whenever he is in his line of sight. I have never owned one of these buggers and assumed they wouldnt be any more aggressive than firemouths, but i have done some reasearch and Ive concluded they are pretty nasty! so how aggressive are these guys actually???? any answers will be appreciated also how fast do they grow and what size could they be ok with my 4 inch jaguar
