OK! I am setting up an octo tank (40 gallon) I do have saltwater experience, a fab 28 gallon nano reef tank. I just set the 40 gallon up yesterday with live rock/sand and a fluval 305. I know I have to wait 3 months or more. My question is what kind of octo should I be looking to add? And where is my best source for purchase? I am sorry if I am posting in the wrong spot, and any help would be greatly appreciated!!
