Checker methodology

How TankFlare grades your tank.

TankFlare is a planning tool for freshwater aquariums. It compares your tank setup and fish list against species data, care tags, and compatibility patterns so the result is more useful than a simple inches-per-gallon rule.

Open Checker
What it reads

The checker starts with your real setup

The score is based on what you enter: tank size, unit choice, cycle status, water test results, filter flow, current livestock, wanted fish, and optional setup details like cover. Species profiles add the missing context, including adult size, schooling needs, water ranges, temperament, fin-nipping risk, care difficulty, and special care tags.

How it grades

A few layers work together

Hard checks catch obvious problems

Some problems should not wait for a score. TankFlare flags setups that are uncycled, too small for a species, outside a fish's basic water needs, missing a school, or likely to create a predator/prey or serious compatibility issue.

The risk model reads the whole tank

After the obvious checks, TankFlare looks at the plan as a whole: tank volume, current fish, wanted fish, adult size, stocking pressure, filter flow, care difficulty, cover, behavior, water overlap, and how much room for error the setup has.

The grade is translated into fishkeeper language

The final label is meant to be usable before you buy fish. Recommended means the plan looks reasonable from the details entered. Risky means it may need changes, experience, or close monitoring. Not Recommended means TankFlare sees a strong reason to rethink the plan.

Under the hood

A trained model, tuned to stay cautious

The risk score comes from a machine-learning model trained on thousands of freshwater stocking plans, each graded Recommended, Risky, or Not Recommended. Instead of trusting a single model, TankFlare runs an expert panel: several models read your plan independently and a final model weighs their opinions together, across roughly 45 setup and compatibility signals — stocking load, water-parameter overlap, schooling needs, temperament, adult size, and care difficulty among them. It is deliberately conservative. A “Recommended” verdict is held to a high bar, and when the signals disagree the model leans toward warning you rather than waving a borderline plan through.

Limits

It is detailed, but not magic

TankFlare cannot see your exact fish personalities, aquascape, local water stability, quarantine history, or maintenance habits. Use the result as a strong planning signal, then adjust with observation and trusted husbandry advice. If the checker says a plan is risky, the safest move is usually to slow down, add missing information, or change the stocking plan before buying more fish.
