I know birds are very intelligent and must be kept mentally stimulated, otherwise they will literally go crazy. It's very sad to watch. They may mutilate themselves or bang their heads against their cage or any number of other terrible things. But then again, birds can live for twenty years, even eighty or more depending on the species, so they're obviously very different. How does that work with Octis? I did read that you should put rocks and pipes in the tank to keep them occupied, is that really enough? I feel that it is very important to provide the best possible quality of life for an animal if you're going to keep it as a pet. Even mice need enrichment - it's been shown over and over that mice and rats that live in an enriched environment have better mental health and are smarter overall. ALSO, after reading through several pages of the forums, I wonder if I might not be able to get an Octi after all. My house is always very warm, because it is very old and the insulation needs to be replaced. There is a five degree temperature difference between the ceiling and the floor, according to my air conditioner repairman. I also have the crank-style windows, which are not very good at keeping air in or out, so I keep the thermostat at 78 during the summer and the AC runs just about all day. I can't afford to keep it any lower, my power bill is about $250 a month during the summer (and my house is only about 900 square feet)! During the winter when I can turn off the AC my power bill drops to $80-100 a month. :P Anyway, I inferred from some of my reading that cooling the tank isn't enough, that the whole environment needs to be cooler, is that true?
