Well, rearranging of stones may become an problem with an coral reef tank, but why not try

and learn the hard way.
Another problem that might occure will be to keep water levels suited for corals, that is if octoes leave as much waste to water as I`we read in articles about them (I`m guessing).
I`m still not sure what kind of speisies I can get hold on from my dealer, there has now not been to many shipments lately sinse the earthquace disaster occured. Thats the area where most of our supplyers are located. But also there is not actually common to have octoes in home aquarium here in Norway so I dont think I get to choose amoung a lot of diffrent octoes

I`m still waiting for my dealer to get back to me.
