hi, I am reading about everything to do with octos... I'm deciding between an octo or seahorses... big decisions. I'm leaning more and more for octos. but, I think I need some advice. I have a 30 gallon sitting around empty, and would prefer to beable to get a octo for that, but through the reading i've done so far... nothing that can live in that live for long (7 months, right?) anyone have any suggestions? I do have a 55, but the problem is that I have a huge fw oscar in it... and she cannot be down-graded in any way, shape or form... 8 inches of fish, that i rescued from a ten gallon aquarium. shes mine!!! hahaha anyway, I have a skimmer (cpr) lots of powerheads, things like that. I've been in saltwater aquariums for awhile... sometimes sucessful, mostly not specially when i had a 3 inch long-tentacled anemone grow to a foot in diameter and kill a good portion of my corals.. I don't know if thats a bad or good thing... I mean, I got a sickly bleached out anem and got it back to health, but I killed a brain coral in the process... anyway, that kinda went off topic. I do have about 2 years of experience in salties. so, if you can give me advice on a 29 gal, how much rock would be good, and what type of oct I could get that would be longer living, and how to get it... I'll do more and more research on that particular spp.
