Great, thanks DarrelHi all,
They are another type of midge larvae and yes the fish will eat them.

They are type of midge larvae, like "bloodworms", but without haemoglobin, fish are keen on them and they aren't a problem.Another bug query if you guys not mind assisting - these came from my outdoor Moina culture, so I assume they’ve been added by a flying insect, but it would be good to know which and ensure they aren’t an issue for shrimp or fish.

Sounds like a <"Detritus worm"> (Naididae).Caught them free swimming (more like twisting and knotting on themselves) before lights on. Have not seen them before but I did disturb part of the substrate yesterday during maintenence.
Look at it against the light, if you can see segments it is an annelid.I'm thinking a nematode?
Fish usually eat them, although they may persist in the filter or substrate.No fish in the the tank
If I lived near the coast I'd catch and use <"Opossum (Mysis) shrimps"> a lot more. You get huge number of them in brackish conditions.I would catch and feed them live and frozen krill (mostly not more than 1-2cm).
Yes. The Great Lakes have Mysis as well - different from the European species, I believe and not as numerous as found in say the Baltic Sea where they seasonally can be found at some spots in such abundance that the water almost turns into porridge.Hi all,

I think the Crangonyx I have are probably as good in nutritional terms, but in ten minutes I could net more Mysis shrimps than I could <"culture Crangonyx in ten years">.

I had the worms in my dosing cup which must have some residual trace mix in it since the worms had died and retracted to the size of a grain of rice within an hour of catching them. So I couldn't check them against the light and have not seen any since.Look at it against the light, if you can see segments it is an annelid.
Nothing to be worried about.So would you say it's likely safe to assume they are nothing to be worried about?
Omg they are cute!Found these little guys in my plant growing tank.
Look like tiny white specs about 1/20th the size of a grain of rice that swim really fast
Might be <"a "Springtail" (Collembola)">, although I can't see spring appendage (it would be tucked up against the ventral side of the abdomen). They are hydrophobic and travel really quickly across the waters surface.Look like tiny white specs about 1/20th the size of a grain of rice that swim really fast
Are these ostracods?
They seem to enjoy munching a dead shrimp as well.. all of a sudden I have a boom of these critters. Guess I need to siphon them out?

Tks for the feedback
Hmmm.. ok …. Just think the little buggers might take over - I have minimal plants coverage (by choice) and lots of white sand so they do stick out a bit when playing around.

They won't take over, they are limited by food source - they feed on bacteria, algae and detritus, so are actually performing a beneficial function in your tank. I'd wager in a few months you end up looking in your tanks and will barely be able to fins one, and then sic months later there'll be loads of them again.
Personally I find them fascinating the way they scurry around with what appears to be real pre-defined purpose!
