Now that my tank is running and I'm waiting the requisite 3 months, I'm trying to source a ceph. I went down to Stagnaro Bros' on the wharf, and met a fisherman there who is willing to catch one for me ("I caught a dozen or so yesterday"). He says they're small (He made a 2"-3" circle with his hands when he said this, so I guess about that size), and reddish. But he sees all kinds. Anyway, my question is: if I get an octopus from him and it turns out to be Vulgaris or some other species that is too big for my (75g) tank, can I simply release it back into the ocean?
