Wow, well after 2 months of disaster I now have the surviving fish in quarantine.

Lesson learned - ALL fish need to be quarantined and clear of disease for at least 2 months prior to introducing to the main tank.

I have 5 humbug damsels and the regal tang left. All the others are dead mainly thanks to Brooklynella. The main tank has to remain isolated from fish systems (and water from fish systems) for 2 months to rid all traces of the parasite. Getting the fish out of the display tank required that I drain it and take all the live rock out essentailly destroying the first 3 months of work. All for the sake of proper quarantine.

I added some more cerith snails and hermit crabs to the tank and then began its isolation. At this rate it will be May before it has fish again.
I also drained the sump, cut out all the baffles and redesigned the layout.


Being nearly all the way back to square one after trying so hard and having only a £100 of dead fish to show for it is devistating, depressing, demoralising and heart rending. Right now if I was able to take it all back to August I'd have used the tank for the goldfish, or not bought it at all.

Hopefully things will be brighter next time.
