Source is Toyops Triops kit. Sand was included. One of the things that was different from the other kits was that it had me throw in small chunck of lime stone (provided), but otherwise pretty standard from what instructions I could find online. I don't know of anywhere local I could get some eggs (USA - Oklahoma) from a private breeder. I have some inbound from Amazon from Greenwaterfarms. No idea if they are any good or not. I got some sera micron to feed them. I am by no means experienced in keeping these guys. Just thought it would be something fun to do, but after several attempts now, starting to rethink my idea.
