Random shrimp like creatures found in the detritus of freshwater sump

[Kingster]

I found a whole colony of TINY shrimp like creatures with decently large antenai relative to body size. They are like a white color and hide in the detritus. How could they get here with no introduction of plants, or shrimp, or sand, or rocks? too small to take a pic. FRESHWATER tank.... tannin water. Thanks I need major help on IDing, have noticed em for past few weeks

Do they look like rolly polly or pill bugs normally found outdoors?

Look up a pic of scuds or gammarus.

Here is a gammarus


If it is pin head size, and has 2 antenna, they may be copepods, I have tons of them living in my sumps.

If they are Copepod's you will see them scoot across the glass.

I had those in my tank, once I added a fish though they all dissapeared I saw the fish chase em and stuff

they dig down, and after checking in my overflows i found a bunch of snails and those bugs, climbing the walls and all

Most small fish will eat copepods, they are great food for fry, and they help break down chunks of detritus in filters that can clog them. Like bacteria, they seem to be ubiquitous, just appearing whenever there is water.

Yep there are a tonne of them, literally 1/50th or smaller of a mm, floating in the water surface or bouncing off the glass. Wish there were more lol. Hope it means my tank is healthy. I used a turkey baster to get some of the larger ones out of the sump, THE MOMENT a tetra sees it, consider it a snack. its bigger then there mouths but only slightly, rarely do they reach the bottom, which i see a female apisto eat the moment she seen it, I NEVER seen they eat so crazily for stuff like this. Will see if i can culture a good population in the sump. I. WANT. MORE.

BTW my female apistos have literally doubled in size and its only been like 2 months

Easy to culture in tubs and barrels, throw in some water,leaves and maybe guppy moss
