Freshwater Fish

Welcome! I am Alex Wayne and I am the founder of Koiusa.com. My team is using personal experience, published studies, and lots of anecdotal evidence from our time spent on fish forums. We aim to deliver the best, most trusted advice when it comes to starting or growing your fishkeeping hobby.

We want to provide helpful information about home aquariums, fish, and other aquatic critters. Our mission is to make complex or confusing topics into clear, easy-to-read guides with no confusing terms.
