You've never turned me in the wrong direction before. I currently acquired a 55 gallon tank and want to make it a community tank. I am used to salt water fish and was looking on some information on stocking fish. I was leaning towards ottos tetras and maybe center piece fish. Any suggestions? How many tetras and ottos can I get? I'm looking for lots of movement. Would two AC110s be enough filtration? Or is that too much for fish so small?
