I currently house a GSP, a Scat, 4 bumble bee gobies and 5 mollies in a 180lt Tank. because of the alcove which the tank sits in im restricted for space. but i was going to have a new tank made, 44" x 18" x 24" tall which will be 308lts. by having 1 corner of the tank rocks for caves and hiding places and the rest free swimming space for my scat (i would like to add another and a couple of monos). what do you think? will the extra height of the tank keep the free swimming fish happy and healthy.
