So We've had GBTA for a few weeks. For the first couple of weeks it was in the rocks towards the top of the tank - no where near where our clowns ever go. Ended up tearing the tank down to get rid of an clam killing, lps munching melenarus wrasse and found a new spot for the nem.It moved around a day or two then settled into a spot in the rocks right by the clown's corner. Sure enough I come home from work and they are all over the nem -which is pretty much the only thing my fiance has cared about since we set the tank up - seeing the clowns in an anemone. Great, awesome.....wake up this morning and found that what was left of nem in an mp40...which wasnt much. I pull it out and the stupid anemone crab is still holding on it, and still alive some how. Really couldnt do much since I had to get to work for a meeting but my water was all cloudy. I actually got up and cleaned out the skimmer cause I heard the lid rattling - I guess it pulled a lot of the nem junk out of the water cause it was only 1/4 full last night, and completely full this morning and had a color and smell that Ive never experienced before. I dumped the crab next to our other BTA (which is a crazy neon orange color) but It never comes out of the rocks. I guess if everything is ok ive now got a good reason to buy a rbta!
