I was doing a water change and some maintenance today and part of that was to trim my Wisteria so it wouldn't crowd the front or the right 1/3 of the tank. One of the leaves I acidentally trimmed while I was going for a stem (this was horizontal growth and I'm rather tall, so it is hard to stoop low enough to see in the tank while my arms are still in it... okay fine, I'm a clumsy oaf 
) is now leaking a steady stream of air bubbles. Is this any cause for concern? Will it heal itself over, or does it even matter as it likey just O2? I am assuming this because unlike CO2 bubbles which tend to grow smaller the higher they climb in the water column (well, that's what happened when I had DIY CO2 all the way at the bottom of this 29 gallon anyway, which made sense because CO2 needs contact with the water to be absorbed) these bubbles are definitely not growing smaller as they rise.
