So I have a 75 gallon Innovative Marine which dimensions are 35.4x23.6x19.7. I have 5 fish in the tank. A Royal gramma a hawkfish(can’t remember the name),a skunk clownfish a six line wrasse and a lawnmower Blenny. I want to add another but not sure what would be a good choice to add to this mix or if I should just stick with what I have. So far I am not having any issues with the current residents so I am anxious about messing with the balance.
