I am waiting on the supplies to get here to set up a copepod/phyto culture and trying to figure out which species I should get to start with. I am thinking Apocyclops would be a good choice but not sure. I have aquacultered rock that came with amazing diversity and also have added the "Snackle Box" from Dinkins so I know there is a diverse population going but with the mandarin in the near future (going with a captive bred so hoping for luck there) I want to be prepared in case the pair never takes to frozen/pellets or needs some supplementation
