Bullseye stingrays are from Australia and are electric. They are very difficult to keep in captivity.My friend had one. Heres a picture. He lived for 6 months,then suddenly died. The tank is 400 gallons.
No celluose if you blanch it. I have had the tang for three years now and never had any issues with his diet. And most landbase lettuces are made up mostly of what? Water. He also likes spinach,peas,mysis,krill,and brine.
