nice tank jay, you need another. Got a small discus setup myself, and a 30 litre converted to marine. Good for a few zoas, a hammer colony, some pulsing xenia, a mushroom, a very small ocellaris, an even smaller filefish for aptaisia control, and two cleaner shrimp. plus the 10% a week water change on the 30 ltr marine is a damn side easier than the 50% on the discus
