I am culturing Nitokra lacustris in 5 gallon buckets for my seahorse fry. They thrive on Reed Mariculture Instant Algae - tetraselmis. The adults average 620 microns in length and the nauplii run about 100 microns and about about 40 microns in width. This species has a short generation time (10–12 days) at 20 C, and produces high numbers of nauplii in water temperatures from 7° C to 33° C and salinities from 10 to 40 ppt. Another species that is easy to raise and grow much larger is moina salina. Be careful about using Tigerpods as they have claws they use to cling to rocks and have been observed (microscopically) clawing their way out of larval fish.

I know I am taking this thread off topic, however this thread is titled "Copepods".
