things i've learnt -
THE BAD:
>mandarins are gorgeous but are hard to keep i've had 2 and both have died (1 jumper,1 non eater), i've added a load of pods and will let them populate for another few months before tryinganother mandy
>Puffer fish - even the small ones eat polyps bigger than them, kill all your crabs and chase fish out of the tank(mandarin) and attack fish 3 times their size (coral beauty), returned swiftly
>Long horn cow fish - looks fine one minutre and dead the next - void they could also take ya full tank if ya not careful (mine lasted 3 days)
>Sweetlips and clown fish don't get on - my nemo killed my gorgeous sweetlips
>Anenomes - are tempremental even with perfect water mine went strange after a week - and i had to remove or risk him taking everything out
THE GOOD -
>MH'S WELL WORTH THE MONEY MAKE YOUR TANK LOOK GREAT
>CLOWNS, CLEANER WRASSE, SAILFIN AND DAMSELS GET ON WELL
>URCHINS, TABLE CORALS, XENIAS, MUSHROOMS AND STARFISH SEEM RELATIVELY EASY TO KEEP
>LOTS OF SURPRISES TURN UP IN THE TANK - SOME GOOD SOME BAD
>vERY RELAXING AND EASY TO DO

THINGS STILL TO DO
>ADD ABACKGROUD
