I have already posed this question in the California regional forum. I live in Southern CA
and I thought it might be fun to have a tank that shows off our local waters. That way my friends can see 'what I see' when I go diving. Has anyone here ever tried a temperate setup? Are they harder than tropical? Does anyone know where you can purchase temperate livestock? I don't think the DFG (Department of Fish and Game) nor my diving buddies would like me if I caught my own. It seems there is not a lot of info out there for temperate aquaria. The only difference I know of would be a chiller rather than a heater. Beyond that I am dumbfounded.
I have also heard that nudibranchs are hard to keep alive in aquariums. If anyone has had a temperate setup did you try to keep a Spanish Shawl? In case you don't know what they are, they are the most beautiful little purple and orange creature and they are everywhere on the reefs in Laguna.
