Hi, I’m Adrian. NanoFishNest is a free guide to keeping small freshwater fish well, written by someone who has bred them and spent years studying how they live.
Who is behind this
I’m a hobbyist, not a lab or a brand. I’ve bred a few nano fish species, and I’ve spent years reading about aquascaping, fish biology and the details that decide whether a small tank thrives or slowly fails. I started this site to put what I’ve learned in one place, free for anyone to use.
What you’ll find here
- Nano fish: species profiles covering tank size, diet, temperament and tank mates.
- Care: setup, water, feeding and long-term husbandry.
- Breeding: what each species needs to spawn and how to raise the fry.
- Equipment: lighting, heaters and tools, judged on whether they work in small tanks.
- Troubleshooting: fixes for common problems before they cost you fish.
How I write the guides
- Practical first. Each guide answers the questions a keeper actually has: how big a tank, how many fish, what to feed.
- Experience backed by reading. What I’ve seen in my own tanks is checked against the research and the wider hobby.
- Corrected when wrong. If a guide has an error or goes out of date, I fix it.
- Free. No paywall, no sign-up, no fish for sale.
Good to know
Some equipment guides contain affiliate links. They cost you nothing, and they don’t decide what I recommend. This site shares hobby experience and is not veterinary advice. If a fish is seriously ill, talk to an aquatic vet.
