I recently ordered some... can you guess? . . . CORRECT. 5260 live copepods and 5000 live brine shrimp. Not sure how they reproduce specifically but I know if I dump 1000 into my sump, they should be sustainable? Wanted to see if anyone who recently set up a new tank would like to get some to benefit their tanks natural shizaams if they dont have any already. These are very high quality show copepods and brine shrimp like those hundred dollar shrooms sooo please try to keep them recycling. They arrive friday or saturday 4/20-21 so I can send them on their tank journeys then. PmPmPmmm. I miss posts sometimes. BONUS: If you are still reading, wouldnt it be great if we could ask someone who aquacultures these to become a sponsor? Will benefit new hobbyists tremendously. I would like to talk to whoever has the power to establish sponsorships and do a collab/joint-effort chat.
