Hi Darrel,

Absolutely superb! Thanks for posting this. It would be good if you could find the one for freshwater tanks.

I've always kept my eye out for anyone selling freshwater copepods or lottle critters like that but never can find them... Other than maybe scuds 🤢. Tint copepods always seem to appear once the aquarium is pretty established though, just wish I could bulster it for my nano fish.

Hi all,

I've never seen them either. My guess is that they aren't easy to culture in commercial amounts.

There is a protocol for using the copepod Bryocamptus zschokkei <"as a bioassay organism">, but I'm not sure where you could get a culture from.

The easiest way to find any Cladocerans, Copepods and Ostracods is to get a plankton sample from near the bottom, in a weedy pond, with reasonably water quality, but I understand that isn't an option for every-one.
Other than maybe scuds
I culture <"Crangonyx pseudogracilis & Asellus aquaticus">, they are easy to keep and smaller than <"Hyalella azteca">.

You are more than welcome to a "starter pack", once this is all over. I can usually find a fair range of Copepods in <"these buckets">.

cheers Darrel

Hi all,
I'll have to remember to drop you a message. Sounds interesting.
I found when I was sending people moss they were subsequently getting Asellus in their tanks , and I've found most of these small crustaceans travel pretty well in damp moss.
We used to deal with Blades at work, and a couple of times they sent us something close to what we had ordered, but not exactly right. I contacted them mainly to tell them that their cultures were contaminated, and they replied by telling me that they didn't culture most of their organisms and that the ones they had sent us were "wild collected" and somewhere on their website there is a disclaimer saying you might not get what you ordered, so it was basically "tough luck". So I no longer deal with them.

So when you pay them £50 for Lumbriculus etc. they then send their intern out to fish some wormy looking things out of a pond for you.

cheers Darrel
