Embed the stocking calculator

You can put the stocking calculator on your own aquarium site. It runs the same bioload and compatibility checks as the home page, works on mobile, and keeps a reader on your page while they plan a tank. Free to use. The one condition is that the visible link back to fishthatfit.com stays in place.

Paste this where you want the tool

<iframe src="https://fishthatfit.com/embed/tool"
  width="100%" height="820" style="border:0;max-width:640px"
  title="Aquarium Stocking Calculator" loading="lazy"></iframe>

Sizing

The iframe runs full width up to 640px and stands 820px tall, which fits the calculator and its stocking result without scrolling on most layouts. Change height if your theme needs it, and set max-width to match your content column.
