Thats sad :( :( Well I guess ill put the archer and the lion fish(if i get them) with the seahorses. I wonder how the LFS keeps 8 cuttles in a small tank, May be I'll get a huge tank. I wanted to buy and octo today( no idea what species) as it was quite big and stil the same price.Unfortunately the octo had what looked like an ulcer on its mantle. :( :( :(
a lot of cuttles can be kept together in a smaller tank, but only for a brief time...there isn't enough room for them to establish any sort of territory, but they get frustrated and sickly very fast.
I think Colin has the right of it...300 gallons or more is the way to go...and hope you live near the ocean, because the cost on sea salt would preclude a lot of water changes! Yikes!
What did you do with the other cuttles?????????????????????
Thats really sad to hear(about all the cannabalism).300 gallons is kinda pricey and so is the salt. Then again it's a huge tank. "no space no space! Y!? Y!? Y!?"
If you go to http://www.cephbase.utmb.edu/biogeo/biogeo.cfm, and search for the Exclusive Economic Zone of Singapore (the last scroll down box), you'll find additional information (range, etc.). Check out CephBase anyway! It's a repository of knowledge for Cephalopod Workers and is often useful even for the hobbyist.
If you can find and keep an Octopus cyanea you will be in for a serious treat! O. cyanea is a fairly large diurnal octopus, sporting a mantle length about the size of a coconut but it is capable of some really wild color changes and even wilder texture changes! They are nearly impossible to get in this country, but through my research connections I managed to acquire one a few years ago. An AMAZING animal.
It didn't last long, unfortunately. My tank went through an 8 month period where it killed cephalopods relentlessly and the cyanea was it's first victim.
