I would really like to know if i can keep any starfish or urchins with my octo? I'd like to know for a lot of reasons most notably becasue they would do a good clean up of missed food and add a cool aspect to the tank... thanks for your input

Someone named Scott Greene had an octo that got high on a chocolate chip starfish:
"One of my octopuses used to get intoxicated (I really think so!) on a Chocolate Chip starfish. He would casually approach, purposefully insert a few tentacles into the central disc, and gradually turn a really ghastly color. I pulled him off thinking he was dead the first time, and it took about two hours before he could move again and regain color. I had not told my wife I had seen this, and several days later she suddenly screamed out to me "The octopus just killed himself!" She had observed the same thing, and felt he did it intentionally. So I filmed him this time as he was curled up in a stiff ball, stuck to the starfish, for quite a while, then VERY slowly inched over to his barnacle, half dead and dangling from it for several hours before regaining color. After I had seen this about four times, I removed the starfish. The octopus was stupid, or an addict."

:lol: :lol: :lol: :lol:

I had a pencil urchin with my bimac last year, and they got along fine. But, as the urchin grew, he began to eat more and more of my coralline algae. I later learned that you need a much larger reef tank (200 gallons) in order for them not to eat a serious percentage of your coralline algae.

Would like to hear others' experiences with octo companions.

We keep very large stars and urchins in with ours. The Giant Seven Armed Star ( Astrostole scabra .......I think!) and the Common Sea Urchin or Kina ( Evechinus chloroticus ) We've never had any trouble with either!

Serpent stars area problem with small octopuses as they are boistrous enough to steal food off them... I removed an 8 inch serpent from a 4" octo's tank for that reason.

Go for the smaller species to start with

The other way round the octi can do a lot of damage to the brittle stars arms .....even a relatively large serpent star can suffer a fair amoount of damage
