I couldn't find a fish food section so I'm posting this here.
I got some Reed Mariculture TDO-B1 and TDO-C1 from their naming ideas website. They were free. The TDO-C1 is 360-620 um which I can feed to my fish. However, the TDO-B1 is 200-360 um. This stuff is like powder. What should I do with it? It is for fry. I don't raise fish. Think i can use it for corals?
