Free APP: Goldfish Tank Size Calculator FULL

Wondering what size tank your goldfish actually needs? The Goldfish Tank Size Calculator gives you an instant, accurate recommendation in gallons or litres — no guesswork, no outdated rules of thumb.

Just enter how many goldfish you have and their type (common, comet, veiltail, bubble eye, telescope eye, and other fancy varieties), and get a tailored tank size recommendation based on real bioload and swimming space needs — not the "1 inch per gallon" myth that leaves goldfish stunted and stressed.
