This past week or two, Ink has become very skittish when I come by the tank. He is still eating about every other day, but I have noticed he has been stock piling any and all shells he can find in front of the cave he now lives in. Almost seems to me like preparing for eggs???? I hope not :( ...but could this be a posability? Did a water change today, and he didn't even come out to see what I was doing except when I left the room. Very un-Ink like. Now that I think about it he hasnt' been plastered to the front watching us lately. I did check my water parameters and everything seems fine. Only Nitrates up a little. Any thoughts??
