I just started my "reef" a couple of months ago, but only got corals into it a few weeks ago. Are there any octopuses that could go in there in about 6-8 months? I have a sponge filter, All ammonia, nitrite, and nitrate readings are 0, 1phosphate, 560 calcium (working on getting it down), 0 copper, and good specs for everything else. Any octos I could put in there in a few months? Also, the only livestock as of now is a small frogspawn and green star polyp. I am able to provide live for it's entire life, but can the smaller kinds be weaned onto frozen? Thanks in advance!
