AqAdvisor alternative: a practical comparison for stocking and compatibility

AqAdvisor has been the go-to free tool for fish stocking and compatibility checks since the early 2010s. It helps aquarists answer two questions: how many fish can I put in my tank? and which species get along? For thousands of hobbyists it was the first calculator they bookmarked, and we still recommend it as a starting point.

At the same time, the aquarium hobby has changed since AqAdvisor's last major update. Larger species databases, modern UI expectations, and deeper tool integrations are now the baseline. This page compares what each platform offers so you can pick the right tool for the size of your project.

What AqAdvisor does well

• Quick stocking percentage. Enter your tank dimensions and filter type, add fish from the dropdown, and get an instant "percent stocked" number. This single metric is why most people visit.
• Simple compatibility filtering. The tool flags known problem pairs automatically (cichlid aggression, fin-nipping triggers, size-predation risks).
• No account required. Everything works on the first visit.

AqAdvisor remains valid for rapid first-pass stocking estimates. Its weakness is that the species list is narrower and the water-parameter basis for compatibility is less granular than what modern databases can provide.

How Aquatic-Art compares

Aquatic-Art offers modular tools for stocking, compatibility, water chemistry, and planted-tank planning. You can open species profiles alongside the calculators to compare care requirements.

Species database

The catalog covers fish, plants, and equipment. Species profiles show available care parameters, behaviour, feeding guidance, and reference links. A missing parameter cannot establish a match between species.

Stocking calculator

Our stocking calculator works the same way as AqAdvisor's: pick your tank, pick your fish, get a load estimate. The difference is that every compatibility factor is also exposed individually: temperature overlap, pH overlap, size ratio, territorial behavior, and fin-nipping risk, so you can see the reasoning behind each verdict.

Compatibility matrix

The compatibility checker shows side-by-side evaluations for any pair of species, with color-coded issue cards that explain why a pair is safe, cautionary, or risky. Each verdict is based on the same engine that powers our static pair pages, so the answer is consistent whether you use the interactive tool or read a pre-computed page.

Tank chemistry tools

AqAdvisor does not address water chemistry directly. Aquatic-Art provides a water chemistry calculator, a tap water matcher, a TDS calculator, and a lighting and CO2 planner, all integrated with the species database so you can compare requirements side by side.

Cost and setup

Both platforms are free. All compatibility and stocking tools remain free without an account.

Summary

Use the stocking and compatibility tools together to assess space, water requirements, and behavioural risks. Aquatic-Art also provides water chemistry calculators, plant profiles, and equipment matching for planning an aquarium.

Frequently asked questions

Is Aquatic-Art a direct replacement for AqAdvisor?

For basic stocking and compatibility checks, yes. The stocking calculator and compatibility matrix cover the same ground. You also get water chemistry, plant, and equipment tools that AqAdvisor does not offer.

Does Aquatic-Art have a mobile app?

Not yet. The site is fully responsive and works in any mobile browser. A dedicated app is not currently planned.

Is my data private when I use the compatibility tools?

Yes. Compatibility checks run on each visit and are not stored unless you save a tank build. No account is needed for the free tools.
