So yesterday all of my cuttlefish decided to ink together several times in a row. Really weird they've never done this. Anyway I changed some water but 3 still did die. I'm not sure if it was the ink or just whatever the heck caused them all to ink at once. I shouldn't say all of them, but more then a dozen inking in a system that is only about 50 gallons was a little much. I have 8 roaming around in their display and I'm moving 4 more over in case water quality is an issue. While I'm sad a few have died it does lesson the burden of feeding so many. Having them in their big tank is better for them but makes it very hard for me to see them.
