Habitat Builder: For Small-to-Medium Sized Freshwater Species

Welcome to our habitat builder designed to help you create and maintain the healthiest habitats for your small to medium-sized freshwater aquatic pets.

We understand how overwhelming it can be when navigating the vast selection of products available in the pet store. It’s not uncommon to receive conflicting or inaccurate advice from store staff who may be motivated by sales targets rather than your pet’s well-being. Likewise, online shopping can be an overwhelming experience, as it can be difficult to determine which products are of the highest quality.

From fish to shrimp, snails and other aquatic creatures, we’ve listed everything you need to provide them with the optimal living conditions they require to thrive.

Learn The Aquarium is reader supported. Purchasing from one of the below links may result in a small commission for us and comes at no additional cost to you. Learn more.
