RBTA are a scourge of my tank's existence. I have a 300G mature SPS reef and can not kill the anemones. I scrape and scrape and cut them out, only to see a dozen new ones pop up all over. They mostly don't bother the coral until it's sweeping the base of the coral, slowly causing tissue rescession and impeding growth. But yes, you can have them together but they are annoying.Okay so I'm interested in eventually putting a couple BTAs in my tank but want to research more on this exact subject. Many people say you need your tank to be mature (6-8months) to start adding any nems. But why exactly? I'm not necessarily asking for just opinions or past bad experiences but what exactly causes a nems to not thrive in a new tank vs an old tank? Where is there actual research of this idea? They get their nutrients from lighting, periodically feeding, and nutrients from the water column so what does a mature tank have that a new tank doesn't that is going to be beneficial to its health? Outside of your regular parameters what else could be an issue causing people to be unsuccessful with nems in new tanks? I ask this because although people suggest having a mature tank I also see people post about adding a BTA to a 1 day, 1 month, 2 month, and 3 month old tanks with good success so what are they doing differently? It's obviously possible I'm just trying to research the cause of failure with nems in new tanks.
