I breed clownfish so I have everything that's needed for that in large quantities. Let me know if u want some for whatever reason u use it for. Trade for corals I don't have or equipment I might need. I need 2 heaters and 3 sponge filter. If u prefer to buy then just $10 for 16oz. I have isochrysis, nannochloropsis, and Tetraselmis phytoplankton. Rotifers, pods, and adult/juvenile brineshrimp.
