I am not for using damsels to cycle a tank. Why? There is other means
to do it without using a fish that in all probability no one is going
to want to keep afterwards. You had live rock, that was sufficieint to
initiate a cycle all by itself so wsa the live sand.

When I was investigating starting my reef tank I was told by one LFS
that they would sell me 2 Domino Damsels for $10 to get my 29g tank
cycled. I was welcome to bring them back in a month or 2 for 1/2
credit. I have to admit I was quite happy with this offer. The store
owner was quite surprised when I brought them back 2 months later and
exchanged them both for a pair of Percula Clowns and an anemone. The
Damsels were doing quite well and were a bit larger than he was
expecting them to be. We had 35lbs. of live rock in the tank, Fluval
204 canister filter, 40lbs of live sand and a Corallife Aqualite
moonlight with a 65w 10K and a 65w Actinic. We let the tank sit empty
for 3 weeks and there was no spike in any reading. We added the Dominos
and we had all spikes as expected in 2 weeks. 6 months later we
migrated to one of our 75 gallon tanks and made the 29 a Molly only
tank.

My anemone was almost a victim of the Fluval intake. We got a foam
filter for it after this incident. A 2nd anemone managed to commit
powerhead-icide. Just when I thought this was too far out of the way to
reach he decided to climb the live rock and jump for it.

Now that we know to feed Chip the Chocolate Chip Star twice a week we
haven't lost any more anemones and the P. and O. Clowns are happy.

OK. Its late and I'm rambling again ...

Back to the point. I wouldn't have even considered cycling the tank
with Damsels until it was suggested by the LFS owner. If it wasn't for
the fact that I wanted the clowns and anemones I would probably still
have them.

Enjoy,
Greg

AFAIK, Damsils are considered "starter fish" because you can add them to
a new aquarium w/ live rock to provide ammonia load and get the system
cycled and running. They are cheap and hardy enough to survive this
environment.

Problem is that they are fairly docile when immature, but grow
increasingly aggressive as they age and can only be kept with other
aggressive species. This blue fin damsel will actually turn black over
time.

As for the offending damsil, I've been planning on a second tank with
more aggressive fish (no corals or anemone), so he'll be my first if he
survives long enough.
