What on earth...

Just introduced the first critters to both of my tanks. Very happy, healthy RCS that I am already enjoying.

But I noticed something just now in one of the tanks that I cannot identify. In the roots of the Duckweed are all these little black specks frolicking around. I have no idea what they are or how they got there. I've never seen a baby shrimp before, so could these be baby shrimp or something else?

I'm not alarmed as they seem to be feeding on decaying plant pieces, and I doubt they would be harmful to any fish. I am just curious what they are.

In my tanks where I have plants at the top I get bugs on them. They really don't leave the tank and the fish sometimes eat them, dunno about your turtle though, the bugs stay small and just bounce around on top of the water and plants. I dunno how to get rid of them, but then they've never caused me any issues and since I have gourami's, betta and livebearers, as well as an angel...they just eat the bugs when they can catch them. lol I often dump water over them and knock them into the water to be eaten.


As for shrimp, I haven't heard of them being up top, typically they stay in the substrate or plants as babies, they love moss balls especially. Babies usually look like tiny,wiggly larvae and then grow into shrimp if they survive. Though it may depend what kind...



Turning on the Aquarium lamp in the morning is MY cup of coffee.

I read something in another thread about Copepods, tiny crustaceans. They're harmless to fish, and having watched them for a bit, they appear to be feeding on the decaying plant matter (dead duckweed, frogbit leaves) floating on the surface of the tank. A very useful task.

I am going to see if I can move some to my other aquarium.
