I squirt in some phytoplankton and zooplex. I see my 3 Trumpet heads feeding. They stay open all most all night long. With the candy cane I've only seen some tentaces around 6am.
My cocoa worm is still going so I'm guessing its getting what it needs from the phytoplankton.
Cant remember the name of the phytoplankton. 6oz bottle that I keep in the fridge.
