Help with marine tank!

[Bob Hollett]

I have a 30 Gallon Tank with adequate filtration, and a protien
skimmer. Lighting is not a problem, and the water tests perfect
whenever I have it tested. I have 7 Pounds of living rock, Bio-balls in

my filter, Copapods (SP?) galore, even have 25 or so baby feather
dusters that have hatched from the living rock. There is green algae,
and no red or brown algae present. There is a marine clam, and red and
blue legged hermit crabs (10 total), all doing excellent. I addition to

the live rock, there are three peices of lava rock, and the floor of the

aquarium is crushed coral. PH levels are perfect, and the water temp
is a constant 75-77 degrees.

The problem is that whenever I put in a fish, it dies. It usually takes

4-7 days to do so, and no evidence of ick or any other disease. The
tank has been set up since the beginning of march, and is well cycled
and established. I'm planning on doing 40% water changes each week for
the next three weeks, in case some other foriegn matter has infiltrated
my tank, but my wife and I don't use sprays or aerosols, so I'm at a
loss.

Any help or advice would be greatly appreciated.

Thanks

Bob, it could be a problem with they way that you are acclimating the fish.
Since they are most likely stressed already from being taken from their
natural home, sent to a holding tank, shipped, added to a LFS tank, then
taken home to your tank, that is a lot of stess on them. What procedure are
you using to acclimate them into your tank? I always use more time than
recommended, and I have been lucky I guess so far not to have any "mstery"
deaths. What I do is add the fish with all of his bag water to a bucket,
then about every 15 mins or so I add 8-16oz of water from my tank to the
bucket (amount depends on amount of water that came with the fish), for
about 2 hours, this will help with any diffrences in pH, S.G., or any thing
else. I then scoop him up like in a cup, like the LFS, and let him swim out
of the cup into the tank.

Hope this helps some,

Hey Bob! did you check for salinity level? and or maybe Oxygen content ( not
enough O2 it may be the problem). Do the fish stay close to the surface?
this is a sign of low levels of Oxygen. hope this helps good luck.
