About TankZen
Fresh water. Clear answers. TankZen exists because finding reliable freshwater aquarium advice shouldn't feel like swimming upstream.
We're a small team of freshwater aquarists who got tired of outdated forum posts, contradictory care sheets, and product reviews that read like ads. So we built the resource we wished we had when we were starting out — a place where every number is cited, every product recommendation is honest, and the writing actually makes sense to someone who just bought their first tank.
Our Mission
Make freshwater fish keeping accessible to everyone through science-based, jargon-free guides. Whether you're cycling your first 10-gallon tank or breeding cherry shrimp in a planted setup, we want you to find clear, trustworthy information without digging through noise.
What We Cover
- Species profiles — care requirements, tank mates, diet, and breeding for freshwater fish, shrimp, and snails
- Tank setup guides — from beginner-friendly starter kits to advanced planted tanks
- Water chemistry — pH, ammonia, nitrites, nitrates, hardness, and how to keep them stable
- Equipment reviews — filters, heaters, lighting, and substrates tested by people who actually use them
- Health & troubleshooting — common diseases, behavioral signs, and when to consult an aquatic vet
How We Work
Every guide starts with research — veterinary literature, peer-reviewed studies, and experienced keeper knowledge. We cross-check specific claims (temperature ranges, water parameters, feeding schedules) against multiple sources before publishing. No guesswork, no copy-pasting from other sites.
Our product recommendations are based on hands-on testing, community feedback, and manufacturer specs. We participate in the Amazon Associates Program, which means we earn a small commission when you buy through our links — but affiliate relationships never influence what we recommend. If a product isn't good enough for our own tanks, it doesn't make the list.
The TankZen Editorial Team
We're aquarists first, writers second. Our team brings years of hands-on experience with community tanks, species-only setups, planted aquascapes, and shrimp breeding. We write the guides we'd want to read — practical, specific, and free of filler.
