AqAdvisor Alternative for Freshwater Compatibility and Stocking Planning
TankMatcher is a freshwater aquarium compatibility checker and bioload planner for hobbyists who want species-pair reasoning, tank-mate ideas, water parameter checks, and stocking examples in one place.
Affiliation Note: TankMatcher is not affiliated with AqAdvisor. We provide a modern, data-driven toolset to help freshwater hobbyists plan successful community setups through bioload modeling and parameter matching.
What TankMatcher helps with
Planning a community tank requires balancing water chemistry, temperament, and biological load. Our tools help you troubleshoot these factors before you buy livestock.
Compatibility checker
Get green, yellow, or red results for species pairs with exact reason codes for temperature, pH, and behavior conflicts.
Try the checkerBioload calculator
Estimate stocking pressure with conservative bioload scores that account for filtration capacity and adult sizes.
Calculate stockingWater matcher
Input your local tap or RO water parameters to find every fish, shrimp, and snail that thrives in your range.
Match waterHow TankMatcher differs from traditional calculators
While traditional tools focus heavily on inch-per-gallon or filtration percentages, TankMatcher prioritizes biological compatibility and territorial pressure.
- Reason Codes: We don't just say "no"; we tell you if it's because of fin-nipping risk, pH mismatch, or predator/prey size ratios.
- Swim Zone Pressure: We analyze if your tank is too "bottom-heavy" or "top-heavy" to reduce social stress.
- Shrimp & Snail Integration: Full support for modern invertebrate-heavy community setups.

No calculator can replace mature observation and regular water testing. We recommend:
- Cycling your tank fully before adding livestock.
- Quarantining new arrivals.
- Consulting structural professionals for tanks over 40 gallons (see our Weight Calculator).
- Monitoring individual fish temperament, as "peaceful" species can have outliers.
