My son asked me today what the little red growths are in the tank. I did some research and I want to say it’s coralline but I’m not confident. Something tells me it’s not a good thing in the tank but maybe I’m lucky? Can you identify the red/rust colored stuff growing? It’s all over the place and it’s starting to grow off the rock almost like montipora.
