I emailed octopets, and asked them about cuttles. I have a 125 gallon reef tank with a single fish in it...but it's crawling with bristle worms (need more help than traps...any fish that eat these?). He e-mailed me back and said that I could keep 2 common cuttles in the tank. I have an over-spec filtration unit that pumps 1200 gallons an hour, and the filters are rated for over 180gallons. I have a UV sterilizer, and two 175watt metal halide lights for the corals. Also, I have two maxima clams...will the cuttles eat these? Though my brother thinks my octo is AWESOME, he doen't want a cuttle in the aquarium downstairs :( ...oh well, maybe the tank is too small even for ONE cuttle, let alone two. That's where I have the question. You earlier mentioned that cuttles should have a 200gallon aquarium...for one. Octopets says that two can be kept in a 125. Humph. So confusing!!! :?
