That is the one Masheer, It is one of the more common inshore fishes on the US west coast, the common shiner perch, but it is pretty and gets about 8 " max. Easy to keep to and if you catch them up in the coastal marshes they are pretty easy to get to light brackish or even full fresh. there are several population living in full freshwater way up in the Sacromental delta, something that suprised the hell out of me.
