ok guys and girls just got a new tank. its a 36" by 17" by 18" tank. judging the best that i can the tank is just over 45 gallons. I went and bout a penguin 200 made by marine land (hope its a good one?????) witha biowheel and have started the cycle now in almost a week. Now i also have a running 55 thats been stocked for nearly 3 months now with 3 angels 4 dwarf gauramis a iridescent shark and a pleco. My question is this..... I want to put my two (kenyi?) cichlids in one of the tanks along with possibly 4 more and 6 cobalts. Which tank wud they fair best in. Removing the existing fish, and filter in the 55 would be worth having the longer tank for the cichlids but i do NOT want the white gravel thats in the 55 with the cichlids. if they would be fine in the 45? i would easily only have to find a darker cichlid sand substrate and then add the fish. Any opinions would be appreciated. Also any recomendations as to a bottom feeder or pleco that would be compatable with my purty lil mbunas?
