Ste2k3 ,
Got two peppermints last night - added to the tank and let them settle in. Switched the lights on this morning and the aptasia was no more. The guy in the LFS reckoned that it might take a few days for them to settle in before they had a go at the aptasia.
Gina,
I didn't want to keep that anenome as they can reproduce like mad - they reproduce using "pedal laceration, a strategy in which small daughter clones separate from the foot of the mother animal" so if you scrape them off you will more than likely leave a load of baby ones. They can cause problems to other reef inhabitants and most people want to get rid of them. People use kalk, boiling water, milliput, etc. or peppermint shrimp, butterfly fish or nudibranchs.
Most of the live rock came from Tri-Mar but I added a few more pieces from a LFS to fill some gaps. I also added a couple more pieces last night - one with some nice polyps and one with some xenia. Pics below.
Thanks for all the nice comments everyone.
Cheers, Eddie
