I'm new to this forum and what I've been reading so far facinates me. But what I don't see any of is talk about keeping squids. How difficult are they to keep in captivity? What type of water conditions are needed for them (S.G., PH, temp, water qual.)? And what do they eat? I'd love to start up an octo tank at some point but I just recently started with a 12 gal. coral tank.
