I have a 32gallon LED Biocube. Right now, I have 2 clownfish, 1 cardinalfish, 1 dottyback, and several hermit crabs. Is it a bad idea to add another fish....or does it depend on what kind of fish I add? I'm also having a really hard time with green algae. It's super hard to remove off the glass, and almost impossible to remove off the rocks. Is there something that I can do to help with it, and/or remove it? I'm wondering if I have it in a less than ideal location, and that is what is causing the algae growth. It's not in direct sunlight, however it IS near a window that gets indirect sunlight for a good period of the day....ugh....\n\nany advice/suggestions is GREATLY appreciated!!
