Hey TONMO,

I've lurked here on and off for a few years researching sepia bandensis. I've probably read "Keeping and Breeding the dwarf cuttlefish" a hundred times haha. So I've finally decided to set up my cuttlefish system. I picked up a 40 breeder with 35lbs of live rock, a 1in sandbed, 150w heater, and an eggcrate top with a fluorescent light. I'll probably be adding a skimmer soon as well.
The plan is to order 10 eggs from blue world aquariums, and then order 100-200 live mysids from sachs aquaculture when they hatch. I'm going to put 5 breeder nets in with 2 eggs each to ensure that they are eating in the beginning.. I'll keep the mysids in a smaller aquarium and feed them newly hatched brine shrimp daily.

I do have a few questions....

1. How long can I keep 10 dwarf cuttles peacefully in a 40 gallon aquarium? Assuming all of them hatch and reach maturity, (fingers crossed :smile:) When should I start cycling a second aquarium?

2. How many mysid shrimp should I order 100, 200? and how long will it take for 10ish cuttlefish to burn through 200 mysids? I don't want to order too many just to have them cannibalize each other.

3. What is the best container to store the live mysids? I was thinking either a 10 gallon aquarium or a 16 gallion black round tub.

Is there anything I missed, or that you would do differently? I'm trying to set up an ideal cuttlefish system, so any questions/comments/concerns are greatly appreciated. I'm excited! :biggrin2:

:welcome: to TONMO

I'm not a cuttle expert so I'll let someone else answer your questions. But I hope you Journal your experience here TONMO.

First things first, A SKIMMER IS A MUST! lol

Second, two cuttles per net breeder isn't really necessary. I've kept them in groups of 6 with no problem with monitoring food consumption. Also, it's good to keep them in groups to establish friendly behaviors in the group. Cuttlefish that have been raised together tend to be more docile to one another.

I wouldn't recommend keeping anymore than 2 adult S. Bandensis in a 40 gallon tank. I'm considering pushing it with 3 (2 females, 1 male), but I'm not sure if it will work out or not. You want to be careful not to overcrowd. I would recommend one cuttle for a 30 gallon, and add one cuttle for each additional 10-15 gallons.

I can't really help with the mysid questions. I live right by Sachs, so I just bought them as I needed them. I never had to worry about culturing or even feeding the mysid. In the beginning, my cuttlefish ate about 3-4 a day. Once my cuttles were about a week old, I had them eating about 10 mysid a day. So I was going through almost 150 mysid per day. However, I've never heard of anyone else having cuttles that ate as much as mine did. I am a believer that you can't overfeed cuttlefish, so the more you feed them, the faster they grow, and the faster they are off mysid shrimp.

Again, storage for the mysid would be different for you than me, as I stored them for temporary (a day or two). I kept them in a 2 gallon cube tank with about 2 inch of water. You would need a much larger container for a long survival time of the mysids, but I'm not sure what size as I have no hands-on experience in this category.

Let us know if you have anymore questions, and keep us updated!

As an octo keeper, I can't add quality to the discussion but there are several good, current threads active in the raising from eggs (DeepBlueWonders' thread among them) right now with discussions on feeding and keeping mysis that are well worth reading.

I don't think this is true, and would be interested in where the idea came from. Also, how is 'friendly' and 'more docile' determined:biggrin2:

At around 4-5 months, sometimes earlier, I see aggression weather the animals were kept together or not. Up until they start showing aggression I move individuals around with no worry.

I would start to get nervous around month 4. If it were me, I would make sure the second aquarium (is it big enough for adults? How many?) at month 3.

2. How many mysid shrimp should I order 100, 200? and how long will it take for 10ish cuttlefish to burn through 200 mysids? I don't want to order too many just to have them cannibalize each other.

That is going to depend on a lot of factors. IF all goes well and you are feeding 4/cuttle/day, that will be 5 days. More of a concern for me is having enough mysids around to handle a mysid die off.

3. What is the best container to store the live mysids? I was thinking either a 10 gallon aquarium or a 16 gallion black round tub.
There is no best. :biggrin2: They would do fine in either, so I like the more gallons option.

My apologies, I should have noted that much was anecdotal information that I originally thought came from one of your articles Thales, although I can't remeber which one.

Ah - thanks! If you ever happen to come across what sparked that, please let me know so I can clarify it! Thanks! :mrgreen:
