I acquired majano anemones as hitchhikers on my LR when I started this tank 2 years ago (not visible at that time). They have spread like wildfire ever since. They have taken over all of the corals that i have placed in my tank. The good news: I no longer have to kill aptasia because they have nowhere to grow. The bad news: These don't look much better than aptasia. Should i have been killing these along with my aptasia for the last 2 yrs? I also have pink-tipped anemones that are overrunning half of my tank. These also came as hitchhikers that I could not see at first. These look a little better than the mojano. Im thinking about rebuilding my tank. Replacing all of the LR but keeping my crushed coral substrate for beneficial bacteria. Should I have any concerns with these plans?
