Thales, one never minds having posts dissected but I find it difficult not to generalize here. I only stated my opinion. I think anyone who is interested in keeping an octopus should visit Tonmo.com, read the journals, tank requirments and talk with other octopus keepers. There are many species avaliable to hobbiests, some which have very specific requirmnets and others that should not be kept at all. It's all in education yourself beforehand. Preperation is the key to being successful.
I see you have a 140 breeding system, thats fascinating! What species are you atttempting to breed? I am very interested your set up, from what I understand, there has been very limited success with breeding in captivity. There was someone who bred bimacs a while ago and there has been some success with dwarfs (mercs). Do you keep a journal?
