HI all! New here but not new to fish keeping. Got my first tank 30+ years ago, since then I've had tanks between 5gal - 55gal. All community tanks, most planted. I got out of the aquarium hobby when we moved year back, my tanks and fish went with a coworker. We built a pond at our new place and have been keeping koi ever since. I finally set up a tank in my office a few months ago and am now working on a 75 gallon here at home.
