Do I need to worry about this algae or remove it?

I've owned Opae ula for about a year now but just came across this forum. I've noticed these thicker algae growing and was wondering if excess should be removed? I noticed the shrimp and my snails love munching on it. Their digestive tract is always filled with it and they seem happy. Pretty active. This is a 5g aquarium with inert sand substrate and shells + calcium rocks. Thanks for the help

You can leave this kind of algae, but it also means that you are either overfeeding or there is some other type of organic pollution in your tank.

Hello. It's been nearly a year. The algae are still in the tank. I do not feed my shrimp. It might be the trumpet snails. I've decreased the amount of this algae by manually removing the bulk of it over the last year. Is this cause for concern?
