Just take it easy on the Vicoden <g>.
I just went through your posts trying to determine:
Size of tank (10 gallon)?
Filtration (20# of LR
) and what else?
How long the tank has been set up? (2 months?)
How was the tank cycled?
When did the cycle complete?
1/27/08 you dumped LR
into the tank. How many pounds did you put in and was it fully cured?
Let's get the tank in shape and complete cycled before adding any additional livestock. Can you take the damsels back to the lfs
for store credit?
I think you get the sand bed down to an inch. The problem is that the beneficial bacteria are in the top inch or so of sand. With one arm and nothing better to do, you could use a turkey baster to suck up sand from the bottom (just an idea).
You should take about a week to get the sand bed reduced, doing a section a day.
Then you should do a 20%-30% water change (get a family member, teammate, someome to come over and help). At this time I would pull the rock and capture the damsels, then complete the water change. You could also try other means of capturing the fish (search on the forums for ideas).
At this point you can work on getting the parameters stable, then you can add A (single) clownfish.
Does this sound like a workable plan to you?
