I decided to improvise, and took 2 large leaves from a silk plant, and stuck them in 2 suction cups and voila! (I scored the top of the leaves' stems to make them bend a little and not stick up... since the suction cups have a hole in the opposite direction as the ones used here and on the in store ones)
My husband's betta investigated it immediately... and settled in for a minute between the suction cup and leaf. Now he's ignoring it, but I suppose they need time to adjust to new things, right?
My betta is ignoring it (I put it on a side of the tank he avoids... I think because of the air stone, so I turned that off as well to see how he reacts) I'll see if he checks it out at all this week with the food trick :)
