Oh price update - nearly forgot.
Fish - £130 (for 5)
Leather coral - £20 (nice big piece with a baby bit sprouting - have teased it off and jammed it in a hole in a piece of rock (gently jammed though))
New lights - £8.50 each (compared to Pets at Home where they were £13.99 each) They're so cheap because they are only standard actinic blue and white and also only 18 inches.
Running cost total:
£427 (give or take)
Bear in mind that I bought a second hand tank though...
That's tank, filter, lights, crushed coral, live sand, 8kg live rock, 2 turbo snails, 2 hermit crabs, leather coral, blue mushrooms and 5 fish. Don't think that's too bad eh? Oh and test kits...
