Beginner aquarium guides written by people who keep tanks, with the numbers you can actually test against.
Most people's first aquarium fails for the same handful of reasons, and almost none of them are about buying better equipment. They fail because nobody explained the nitrogen cycle before the fish were already in the tank.
Aquarium for Beginners exists to give a complete beginner one trustworthy place to start — in the order things actually matter. Choose a tank. Buy the few things that count. Cycle it properly. Then, and only then, add fish.
We are independent and reader-supported. We accept affiliate revenue from Amazon and other retailers when you buy products we recommend, but affiliate links never determine what we cover or how we rank it.
Water-parameter ranges, species temperaments and adult sizes are checked against primary references — peer-reviewed aquaculture and fish-husbandry literature, published species databases such as FishBase, and manufacturer specifications — rather than repeated from other blogs. Retail tags on fish tanks are frequently wrong about adult size; we say so where it matters.
Where we recommend a filter, heater or test kit, we say whether we have run it ourselves and for how long, or whether the recommendation rests on specifications and the consensus of long-term keepers. We do not present the second as though it were the first.
Prices change. Where we quote one it is a range, and the modified date on each article reflects the most recent substantive update. Always confirm the current price with the retailer.
Every article carries a named human byline. Our authors use AI tools as research aids — drafting outlines, surfacing cited sources, producing first drafts that a human then verifies and rewrites — but no article is published without a named editor reading it end to end and standing behind the claims. We do not publish anonymous AI output as fact.
Some product cards on Aquarium for Beginners link to Amazon and other retailers via affiliate programs. When you buy through those links, we may earn a commission at no extra cost to you. We disclose this on every page that contains affiliate links and we do not accept payment for product placement, ranking position, or favourable reviews.
If you spot a wrong parameter, a stale price, or a species recommendation that shouldn't be there, email editorial@aquariumforbeginners.com. Substantive corrections are noted at the foot of the article along with the date the correction was made.
Aquarium for Beginners is published by a small team of fishkeepers and writers. Each author has a profile page listing their areas of expertise and a complete archive of their work on the site.
