Leaves creating bubbles, Is this dangerous?

[IJC]

Hey, so while i’ve had a fish tank for like almost a 7ish months now but, i still considered myself a beginner. Recently i upgraded my tank to a 29 gal and had questions about neon tetras . I was recommended Indian almond leaves, which i recently put in my aquarium. I have three in right now and have noticed some bubbles at the top of the tank which online says are from the leaves. Although i can’t find an answer for if it is dangerous. So is it or is it something i can just leave

It is not dangerous, though I doubt the bubbles are coming from dried leaves. Bubbles from live plant leaves are oxygen being released during photosynthesis, but a dead leaf is not going to be doing that. I suppose it might be CO2 from the decomposition of the dried leaves, I've never seen this but it may be feasible. Bubbles that appear all over the place right after a water change is CO2 dissipating out of the water; tap water can have a lot of dissolved CO2. None of these are dangerous.

If there is any kind of 'curtain bubbler' or air stones being used it could also be very tiny minute air bubbles attaching to the leaves.
