I am looking for a good suggestion for a skimmer for a 2g cube. I have looked around and most of what I am finding is a bit on the big side. Any suggestions would be great.
IMO you dont need a skimmer for a 2 gallon tank. With a tank that small the very frequent water changes should be enough. Might try a small power filter like Azoo though for extra water cleaning.
I know of no skimmers small enough to fit on/in a 2 gallon tank. But I would agree water changes. You could do a 50% water change every week and have better water quality than most tanks with very large skimmers.
