so far i have the jag, the jd, a spotted raphael(very cool fish at least it was in the bag i havent seen it since) and i am down to two guppies. if the jag doesnt get along with the jd i have options my sump will be a 6 ft long 125 with about 3 ft dedicated to a vegetative filter so she could go in there or i have a spare 46 gal bowfront she could have all to herself. eventually the 300 will house a midas and a pike cichlid as well as for non cichlids prolly a large school of silver dollars.
