Hello everyone, I'm glad I found this site as I have just recently acquired a Bimac Octo. I am a reefer so I have some experience with keeping saltwater tanks and strict water perameters however, I am not completely familiar with keeping Octopus. Here is what I have done so far, I went all out and dropped some cash buying a UNI 50gal. Total I filled it with 35gal. of water. 20 gal from my reef tank and 15gal from LFS. The remaining space is displaced with live sand and live rock. I have been putting NUTRAFIN (cycle) into the bioballs. I experianced an amonia spike this morning but this evening it is decreasing. Obviously, cycling the tank with OCTO in it is not the most desireable but at this point don't have to much of a choice unless I release him. He has been in captivity since Thursday Apr 19th, been in this tank since Apr 21st and today is the 24th so far so good he seems to be doing fine. He has eaten some blue damsels I had in tank a turbo snail and yesterday I placed some mussels from the same waters he was taken from along with some fidler crabs. He has not eaten any of those yet. Water temp. is at 72 and salinity is at .026 I am praying I am doing everything correct as I do not want to lose him. In just the last few days I have come to the conclusion I hope to always have an OCTO in this tank. Any advice/guidance would be appreciated.
