Wonder if any of you can help me. Every now and then in my tank I hear a click noise. Sounds like it is coming from inside the tank, almost like a stone hitting a window.
Do any of you know what this might be? It has started happening after I got my green star polyp, so I'm thinking something has hitched a ride into my tank. Any ideas what it could be? I have seen this small orange looking thing darting about, though no idea what it is as I can hardy see it.
