Thanks for the interest! The cycle is progressing, had the ammonia spike but no nitrate spike yet. I am not sure what exactly the live substrate is but it is sand and did come from an established ceph tank. The bag at the bottom is some extra that I'm storing. Picking out some items for the future cuttles now (cave, coral, etc.) so any suggestions are welcome.

Hello Col. Cuttlefish!

I culture S. bandensis (along with euprymna and some other species) in my lab in San Francisco. We feed them live food only (mysids and grass shrimp), which we get from Aquatic Indicators in Florida - they are a super vendor and highly reliable. We buy Sepia eggs as needed from wholesalers, but our adults also lay eggs in our tanks. We have two systems (450 gallons and 600 gallons), and we keep about 80 animals at a time. Out of interest, how many are you planning to keep in that tank system? It looks a little on the small side but if you are only planning on keeping juveniles, it's fine.

If live sand is your source of cycle, did it come from a bag (I see one one the pic) or from an established system with the same temp and pH parameters? The 'live sand' from the bag is questionable for establishing a cycle. I also think the shrimps are probably not enough biomass to generate a solid cycle that will cope with the intro of cephs - they are very dirty! I would buy some uncured live rock and let it die off in your tank for 1 month to establish your cycle, but opinions on cycles vary widely...

Do you have a skimmer? You will need one to remove the slime and ink from the water. No need to set it up during the cycle though.



Good luck with your cuttles!

We are only planning on keeping a handful, we will probably use the eggs for most studies. Thanks for the recommendation, finding solid vendors has been a bit of a struggle. The tanks are all connected and there is a filter with filter floss, activated carbon, and a biofilter. Do you think that will be enough or do you recommend a skimmer also?

Protein skimmers are often debated in the marine hobby but not for cephalopods. No other filtration method cleans up the ink as well.
