I have had some problems with my xenia and some fish dying over the past couple months but things have settled down, xenia now spreading and attaching to multiple rocks Pajama cardinal is still a soldier and my yellow watchman is a spaz but doin well. Anyway, was wondering if a catalina goby and or peraly jawfish would work well in this tank or would that be too much of a bio load with those 4 fish. i really like the catalina gobies their pretty colorful.
