I'm currently a student in the Oregon Coast Community College Aquarium Science Program. For our life support class, we are building a temperate cephalopod system. The system consists of two 250ish gallon fiberglass tanks. In the first tank, we plan on housing locally collected juvenile GPO's before they head to the Oregon Coast Aquarium or the Hatfield Marine Science Center. In the second tank, we have been discussing keeping S. Officinalis. Does anyone see any problem keeping them in the same system? Thoughts on the optimal temperature to keep both happy? On raising S. Officinalis, how different are they from raising bandensis? The amount of food is not an issue as we are located on the Oregon Coast, but I want to make sure I have a steady supply of appropriately sized foods. In the beginning I'll be raising these guys in our smaller coldwater invert system, but how many adults would be appropriate in this size tank? Thanks!
