These two were given to me, but I have no idea what they are. Does someone have an idea what plant species these might be?

The plant below is supposed to be green, this one is dying so it turned yellow/brown, but it's kept as floating:

First plant is a Hydrocotyle sibthorpioides. I have it in my tank and it grows really slow. Not sure about the second.

Hydrocotyle sibthorpioides needs very good light and soft water. It can be very hard to grow and as said grows slow.

A better pic of second plant would really help like what the plant undeer the water looks like.

Thanks, konrad and da oz. I'll look the plant up. I'll try to take another pic of the second some time and post it, but the plant seems to be dying, so might just throw it out...
