So my frogspawn has gotten huge lately as has my leather. The right side of the frogspawn is starting to get into the shadow of my leather. Up until a few days ago I have never seen the frogspawn put out sweeper tentacles before. Now, the side that is getting shaded is putting out 3 or 4 of them. Last night one of them was 3 inches long. It moved around in the current until it made contact with the leather and stuck to it. A small sectin of the leather got stung and its tentacles retracted. It looks fine today. So I was wondering if the frogspawn actually detected the shading from the leather and decided it was time to go to war. Has anybody else seen this behavior?
