Stock

These Stock pages are for selecting your livestock. If you need to add a component that is not one of these types you can add it on the Build page.

If you would like more validations and compatability information you may want to try out this site:

That site is really helpful on making your stocking choices based on their compatability with each other and your tank size, filtration, temperature, ph, hardness, and more.

Like System and Scape these Stock pages support an "Add Custom Component" feature. If you have something other than Fish/Snail/Shrimp to add you can do so on the Build page.
