i haven't bought the nudibranches yet altho there's still quite a handful available in the LFS. we're still contemplating after being told about the sponges as well. different LFS owners tells different story.. some say they survive on algae or whatever we feed the fishes.. some mentioned about the sponges, which is also available at high price.

see how lah... very tempted.... saw one bright shocking purple nudibranch, damn cute! arrrggghhh....

erhhm...btw, i'm no bro to u, i'm sis! haha
