HI all! I just moved into a house that is large enough for me to start getting into my fish hobby. I already own an empty 30 gallon tank, but I’d like to purchase 2 to 3 more tanks over the next year or two. My question is what tanks would give me the best variety in terms of size what I’m able to keep in them? If you’d like to recommend some specific fish to house in them that would be great too. I probably won’t have room for anything larger than a 55 gallon. Thanks in advance for your suggestions!
