White little mites running around a piece of driftwood in 7 gallon aquarium

[jv85]

Hi! I just realized that a colony of tiny white little creatures (that look like mites) living in a piece of driftwood in my aquarium. I was wondering if somebody can help me to identify if this should be taken care of. Or, if it is part of the ecosystem. It is a 7 gallon aquarium with a HOB, a few pieces of driftwood, river rocks, and a few aquatic plants like java fern, tiger lotus and anubias. I would provide pictures but at this moment can't. I'll post them if somebody answers.

Thanks!

Pictures would definitely help for a more precise answer. The white creatures could really be anything without specific details, could be scuds, copepods, or a plethora of other critters.

The tiny white spots are the critters. They swim and crawl around the wood. They move very fast considering their size.

Could be seed shrimp.

Thank you Daniel. If they are seed shrimp then no harm there and I will let them be. I first thought they were parasites. I used Expel P yesterday and today I saw the creatures. So I thought they were reacting to the medicines. But I will keep it under observation. Thank you very much!
