Compatibility checker
See what can live in your tank
Before buying fish, plants, or products, check whether tank size, water values, and difficulty really fit.
What we check
Minimum volume, water parameters, difficulty, behavior, low-tech or high-tech plants, and useful products so you do not buy blind.
Before you buy
Use the checker as a quick filter: if something looks off, open the species profile or parameter guide before going to the shop.
What fits your tank
Indicative result: always verify behavior, adult size, and real tank conditions before buying.
Frequently asked questions
How do I know if two fish are compatible?
Check volume, temperature, pH, hardness, adult size, group size, and temperament first. The checker highlights the main risks.
Does the result replace expert advice?
No. Atlarium gives a practical first assessment based on available data, then you should confirm with species profiles and real tank conditions.
Can I use it before buying products?
Yes. The configurator connects volume, light, CO2, and tank goals to products and guides already present in the portal.
