What's up with my frogspawn?

I have noticed one of my frogspawns polyps may look cut. I am wondering if maybe my Mp10 caused it.

It's hard to tell from the picture. Could you get one with less blue?

too close to pump

Yeah, or a fish took a quick snip. Either way it's perfectly fine; once, during a water change I sucked up accidentally half of a hammers fleshy tentacles, grew back in no time.
