How big is Einy? Dan's are quarter to half dollar sized, but then again, Einy looks very young.

Einy has the tiny "horn" over each eye, and very long skinny arms, little to no webbing really. Sometimes I am almost certain I see texture on his mantle, between his eyes. It seems the white spots on his mantle raise to form points much like the papilla over his eyes.

There are several dwarfs that would do well in a 30 gal system. They inlcude O. mercatoris, O. bocki, O. wolfi, O. diguite, O joubini, etc. However, all of these species are shy and nocturnal. I would not recommed them for an aquarists interested in observing and interacting with the animal they are keeping. The two commonly available species that might just squeeze in, provided that your system is rock stable are O. briareus and A. aculeatus. Both are moderate in size, interactive, and are commercially available.

Well, I was planning on joubini for a 29 gal. tank. How many could I put in there? If not those, are any of the other species easily kept? And how many of them could I put in a 29 gal tank?

Well, I finally got a new seahorse for my 30 galon macro tank, so if I do get a dwarf i'm using my 10 gallon. There are a few I have my eye on... just need a little more money. I was set on putting one dwarf in my 30 gallon; just worried i'd never see it though.

I think Einy would be okay in our 30 gallon with one of our seahorses, but as stated, don't know if you'd ever see him.

I just moved my O. Mercatoris out of the 10 gallon back into the 75 because he never would come out of his shell. Inside the critter keeper I see him watch the fish swim around. So, I would say they do better with some kind of activity going on around them. This is my first octopus experience though, and it could be an individual characteristic of his.

I don't plan on using my 30 gallon for a dwarf octo. It's heavily stocked with macro and live rock- I would never see it. Plus, my new seahorse is a tiger-tail (Hippocampus comes), and I don't want to risk anything with it seeing as they're more sensitive than reidi etc. and I just want a species only tank ATM.

Dan, i'll keep you on my list. I may be getting a joubini, idk. I'm also possibly taking in a small package of dwarf seahorses and dwarf pipefish- so i'll have to see what's going on.

Ok, I'm confused. I was told that Mercs got to be softball sized.....now you're all saying quarter to half dollar sized....Is the quarter to half dollar not inluding the tentacles?

Be sure to sterilise your tank.Cephs can be rather prone to vibrio infections. We use bleach in the tank for a fortnight, then neutralise it then we fill with freshwater for a week, then seawater and reseason the tank and plumbing. All nets etc should be treated in the same way (sorry if I'm preaching to the converted but I would hate for a new octopus to pick up a vibrio infection as they are almost impossible to cure). We tend not to put cephs in with our horses but we have a giant species (H. abdominalis and our midget octopus are moderately aggressive, our other octi species gets waaaaay too big 2.5m +!).

Cheers

Jean,
What type of antibiotic is safe for the octos?

I keep a small supply of meds for the seahorses (mostly used for quarentine but I have had an occassional scrap to tend to) and have some clue on using them but I haven't seen anything written up for the octos for treating (or attempting to) infection (aside from vibrio which seems to be untreatable in all fish) or skin lessions. I don't think there was anything I could have done for JoeJoe but it did make me think to ask what meds are considered octo safe.

Thanks,
