The prolifera is proliferating and has already taken over the mangrove tank once, and is well on its way again. I added some to the fuge you can just see it peeking over the LR in the second pic, and I also added some to a sand area in the lagoon. My Queen conch did too much damage to the rhizomes of the shoal grass and there may be one small piece left in the mangrove tank. The Halymenia was growing well so I split it. There's a few fragments growing in the mangrove tank a large piece in the lagoon, and there was a large piece in the fuge. I caught my queen conch munching on it, she chewed off all the little fronds, and now I cant find the main piece. It was in there when I moved her to another tank so I think its caught behind that piece of LR.
Those queen conchs are rascals the one in my lagoon munches on the prolifera, it destroyed the shoal grass, I have seen bite marks on my Thalassia when my snails bring a leaf down low enough for it to get at, and one rhizome didnt even send up leaves I think because the conch eats them when they try. She does a great job keeping the sand bed spotless though.
