Oh yeah, I forgot to mention that I will also be dosing my tank with homegrown phytoplankton that I will culture... This will hopefully feed the zooplankton which will hopefully feed the 'pods, which will end up as healthy snacks for my pipefish. If anyone that's kept these guys is interested, here's my build thread for your consideration... http://www.canreef.com/vbulletin/showthread.php?t=45990, and I may yet start a thread about the care and behaviour of these interesting tiny beasts.
