Homepage FAQ

What is AquaIndex Score?

AquaIndex Score is a point-based 0-100 score that combines Nutrition Fit, Ingredient Quality, and Practical Suitability using a 40/40/20 weighting.

How do you handle missing nutrition or ingredient data?

Missing data is excluded, not penalized. If a component is missing, AquaIndex excludes it from scoring and shows that exclusion clearly.

Is AquaIndex independent of fish food brands?

Yes. AquaIndex is an independent comparison tool. Scores are generated from a consistent, transparent methodology rather than brand partnerships.

How do I choose the best food for my fish?

Start with your tank profile and diet group, then compare foods by score, nutrition fit, ingredient signals, and practical suitability in the comparison tools.
