The Rainbow Goodeid is a vividly coloured freshwater fish endemic to Mexico, beloved in aquatics circles and critical to conservationists due to its highly restricted range. A member of the Goodeidae family, it’s a flagship species for freshwater habitat protection.

What makes rainbow goodeids ‘rainbow?’

The males display iridescent colours—golds, blues, and reds—which shimmer like a prism in motion.

Do Rainbow goodeids lay eggs?

Rainbow goodeids are a live bearing fish, which means they give birth to fully formed live fry, rather than laying eggs.

How do Rainbow goodeids contribute to the ecosystem?

Rainbow goodeids help to control insect populations living within their habitat, as insects make up a large portion of their diet.
