I'm back to growing chaeto only & a couple mangrove for my shrimp to climb on, after recently having much of my caulerpa go asexual on me overnight. I have about a 4" sandbed with live rock, 1 peppermint shrimp, snails & hermits. There may still be a couple pieces of caulerpa, red gracica, tea cup algae, & dragons breath, which will take off again eventually. I also have 1 skunk clown & maybe a 3" black & white serpent star I haven't seen in 3 weeks.
