@Dexter is 100% correct the inevitable happened, the clowns were getting to big for the cube and i could not justify having them in the cube anymore.
So last week monday all the clowns were sold and are now happy in one massive maginfica in a 2m tank. At the time of sale there were still the original 15 i started off with a year ago were still all there.
After chatting to the buyer on monday evening he also suggested a trade for most of the nennies to which i could not say no too.
Now i have an lps dominated tank with about 4/5 nennies in.
On saturday, after 3 years i finally bought the fish i have always had a soft spot for....a blue mandarin goby!
