My wife has been interested in getting a pufferfish for a while now, so we've decided to start with a small porcupine puffer. Currently, we have a medium-sized hippo tang and a few clownfish in our aquarium, and they have been with us for a few years. As my wife is concentrating on stocking the upstairs tank, I am thinking about what fish we should add to our smaller 65-gallon aquarium downstairs.Hi Andrew long time lol. Nice tank! Have you decided what fish to add to the 180?
