My friend has a baby snapping turtle and has asked me for some advice becuase I have a RES. His baby has algea growing on his head, I've never seen this before. Its bright green. The turtle has a pretty good set up, places to hide, basking area with a heat light, not too deep water (this turtle is tiny) I suggested that maybe he needs a better filter so I'm giving him one of mine for now, and that perhaps the turtle just needs to get out of the water and dry off and let the algea die. I'm not sure what to do, the turtle never gets out of the water. My turtle basks all day so I've never had a problem. Any help is muchly appreciated.
