Thank you!!!!! That anenome is small now, but it will grow and you will eventually need to move it into a bigger tank. Otherwise it will move around and sting the $%^% out of the corals. Wow, I had no idea......and I was thinking about fragging my zoas. I have a huge (by my standards) rock that needs to be divided up. Thanks for the post (warning). You should only have one, maybe two fish in there IMO. You are still overstocked. They will start competing for oxygen....it's not just a waste issue. I am going to say when here, because it is obvious that you are hooked and there is no return (this is a good thing). If you want to move to the 15g, cool. It will give you a bit more room to move around in. I was about to ixnay the idea until I realized it was not a 15g tall. I have one of those. Not the best set up. Now, there is something I want you to do. Look around the forums at what we other members have. Look at Packleader's 46g. Look at my 90g. Look at KOgle's (is it a 180?). There are all shapes and sizes here. There are budget models and there are top of the line models. Pay really close attention to the hardware we have and familiarize yourself with all of it. And I mean all of it. There are also differing requirements that come with the different tanks. For example, skimming and lighting become an issue with the larger tanks. It is possible to spend over $1000 on a lighting system for a 90g tank. Skimmers for the bigger tanks can cost new up to $500 to $600. Now I know you are not going to jump in and spend the thousands of dollars it takes to completely outfit even a medium size tank, but I just don't want you spending your hard earned cash on something that you, essentially, already have and regret it later. These days, money is hard to come by and it doesn't spend like it used to. Just something to think about.....because my friend, it seems you have reef fever, like every one of us here. It is safe if you clean it out with a good soap (someone else is going to have to chime in as to what kind) and rinse, rinse, rinse. You do not want any soap residue at all when you transfer your livestock. If you decide to do it, we can go over the proper procedure of transferring a tank. It will be easy with that size. You will be able to keep five to six inches of fish and pretty much as much coral as you want. That anenome will outgrow the tank at somepoint though. Get ready for that.
