Hey guys my frogspawn was a darker green when I first bought it. Now it looks almost translucent green. Im trying to understand why the change in color? Its in an area where there's not alot of water flow and it still fully opens. Any help would be appreciated. Water parameters are good across the board and I have 75g and I have it on the sandbed. Should it be closer to the light? I have t5 light setup.
