awesome..for a second i was hoping it would be the blue ringed octopus in your avatar. i have kept a few and found them to die easily. one actually laid eggs and we got tons of babies. not sure what species i had though but it got to the size of a basketball. i would love some info on keeping them and the hardiest species with profiles. how long have you have yours for? how big will it get? what are the things crawling on your glass?
