Innovative marine silicone leaks?

[HereFishyFishy3]

Hi everyone!
I recently bought a used innovative marine rimless 20 gallon aquarium. As I was cleaning it, I noticed some “gaps” in the silicon. The gaps are on the front of the aquarium near the top. This is the largest gap but there are some smaller gaps further down. Should I be worried about this or am I being overly cautious?

I wouldn’t worry about that

Thank you for your reply! This is my first rimless aquarium, so the advice is greatly appreciated.
