What size of aquarium is appropriate for breeding S.Officinalis and for keeping the babies?

i'd say at least 300 - 500 gals for breeding them, preferably round plastic ponds and as large a tank as possible for rearing larvae... with a good source of food!

Welcome to TONMO.com, what have you got in mind?

Yeah, please share!

Thanks for the quick reply and your useful advice.I think about getting two of them by fishing and then introducing them to a 210 ltrs marine aquarium that I recently baught.In future,I wish to have the chance of owning such a big tank.

Where are you located henry?

In Greece.We have a lot of Sepia Officinalis in our coastal waters.They are found literally in all beaches of my coyntry.
