I am starting a 10 gallon tank. I have five tetras and an elegant cory. I want to add at least one fancy guppy, but that will be about all my tank can take. So, I am wondering if my cory will be ok without any cory buddies to hang with. He darts in and out of the tetras occationally. I really dont want to add another cory because they get to be 2 or more inches long and thats 2 or more other fish I could have in my tank. Am I making any sense? You can tell I'm new at this cant you?
