Octo set up, will this plan work? I recently read an article in an old fish mag. that was on octopi. It said that they are eaiser to care for than most people belive and that all you really need is a carbon outside filter and a u.g. filter. Based on this info, this is my plan. I am going to set up a 20gal long tank with a u.g. filter (attached to the bottom of the tank and all parts sealed togather) with a power head to run it. A millium 2000 back filter, crushed coral for the substrate, and pvc pipe for hiding places. I was going to cycle the tank with shrimp for about a month, and then put in a star fish and some mollies. Wait another month and if everything is still in tip top shape I am going to order an octopus. I will try to get a Bimac, but it seems to me that they are hard to get. Any way, do you think this set up would work? People have been telling my you have to have a skimmer, but I do not see why if you do weekly water changes (something I already do on my reef tank). Any way, let me know what you think. Jacob.
