Bugs in planted aquarium

I got this bug swimming on the surface of the water in my planted aquarium. I'm not sure about the species of this bug at first, but I searched on google as water bugs and came up with the result as Gerridae or Water Strider (Gerris remegis). It seems harmless to the floras and faunas in your tank so I just ignore it. This is some shots of the Gerridae or Water Striders in my tank. You can read more in Wiki about this creatures here: Gerridae

Microsorum pteropus (java fern) & Marsilea hirsuta pearling

Some shots of java ferns and marselia hirsuta pearling.

 When there's enough lights,and percents of co2 in the water, photosynthesis occurred!
