Okay so i decided ill be going for a 15 gallon salty only, maybe a 40 but no 75 as the costs are too high, on equipment it shouldnt be too hard for my 15 gallon fluval (freshwater atm) i just gotta change some filters, put on a heater, reef lighting, a wakemaker and the equipment for testing etc. Im planning on keeping softies or lps and i was planning on 2 clowns and a fire fish or a royal gramma, would that be fine for a 15 gallon? If u guys have any suggestions on equipment or my stocking choices do let me know.
