I don't know what kind of fish it is
What are algae eaters? They're those big black fish in tanks, which I've mainly seen at walmart, petco and other places. My dad had some at one point back when he lived out here where I do (then had to move because of work and I don't remember if he still has any fish left). I figure that they're kept to get rid of algae, which is the whole purpose of the name, but what are these fish and what do they even do?
