Yeah as I writing above about seems easy to remove them if they get out control ( I went from yeah if some corals like xenia, gsp,or clove polyps get invasive it's not like one day you got 4 polyps then next day look at tank and you have 200 lol ) to then thinking about all the threads I've read about people using flux ( can't remember correct name/ spelling ,fluxtocene or something ) to remove their invasive clove polyps.
I've read like keep xenia on its on rock so doesnt spread all over main rockwork ,but read they can detach themselves and just float away and land on main rock work anyway ,gsp ovbiously seems little easier as can often just peel/ cut it away especially if on flat surface, bit seen some say if some gsp left in crevices of rocks can grow back from little nub.
So back to clove polyps, what makes it so hard to remove if gets to much or whatever reason want trim it back or remove ?
Is it because how it reproduces sending out runners and they can be some left in the gaps/ crevices maybe ?
I'm asking as I really like look of firework clove polyps and often when go lfs to buy corals like last weekend for example seen a few different clove polyps and always get attracted to them and nearly buy them each and everytime ha ha
