Well, fear not my dear readers, for today we are going to dive deep into the world of sucker fish and answer all your burning questions.
Firstly, let’s start with a bit of background information. Sucker fish, also known as catostomids, are a family of freshwater fish that can be found in rivers and lakes all over North America. They are easily recognizable by their large, sucker-like mouths which they use to feed on algae and other small aquatic organisms.
