Rice size brown bugs

[Jekyl]

Would be about impossible to get a photo. Just noticed a bunch of these in various sizes on my rocks and in the CC substrate. Have legs and move pretty quickly. Sizes vary between smaller and almost the size of a grain of rice.

Amphipods or copepods which are food for certain fish and inverts. Part of the delicate balance of nature in your aquarium and good to have!
