So my rainbow shrimp released last week and I removed some into 2 separate containers and left some behind in with the adults. both groups i removed seem to be gone now and the ones with the adults are mostly gone now. i was assuming most of the predation would come from the adults, but now i wonder if its not copepods. I have them everywhere and didn't really think much of it, but some of them got carried over with the zoea when I removed them and since there isn't anywhere to hide I now wonder if they ate them.

I don't know what these things are, but they are about the .15 cm at maximum size and mottled in color. the whizz around the tanks and i never try to get rid of them since they seem to help clean up an extra food and never bothered any fish fry. I first noticed them when i started feeding freeze dried tetra daphnia. After that they showed up in every tank i used it in and eventually they have spread everywhere. Non of my fish eat them.

So i'm wondering if I should start a new sterile tank and move the adults. I think this one is a lost cause and am just about ready to hit it with some bleach to clean it out.

well, i am either blind or they were hiding behind the sponge filter, because the larvea showed up again today. i suppose the copepods aren't a problem after all.

When your 2 or 3 mm it's very easy to hide.
You probably have a lot more then you think you do.

Copepods are not the problem. The babies do not like your water parameters. What is your hardness, pH, etc.

well, i'm going to sound like a blasphemer to some, but i don't watch water parameters, i just do my changes and get on with it. all of my water is hard and above 7 somewhere (soemthign like 7.6 i think). i have some dehumidifyer water and peat water i use with some killies, but everyone else gets the regular stuff, unless i'm tryign to do a rainy season thing with tetras or cories. pretty much everything i bring home breeds for me, so i suppose there's no complaints form the inmates.

they turned out to be ok though. found a whole swarm of them in there. i want to bump them up to a bigger container soon though. i don't want the waste production to sneak up on me.
