Is this glue safe for my tank?

[bloodlucky]

I did a DIY fry trapper that traps fry that are running around loose in your community tank. Anyway you need a water bottle. I peeled off the Dasani sticker but there's a little glue left behind from the sticker seal or whatever you call it. I boiled the glue area an scratched off as much as I can. Am I all set to use this now?

I just put it in all the fish look fine but I couldn't wait for answers because the platy is probably going to give birth tonight while I'm asleep
