Amm, nitrite, nitrate are stable at 0,0, 10 ppm, ph 8.4, ca 375 (working it up with an additive slowly). 4 weeks ago I added 5 snails and 2 fire shrimp over a 7 day period. These have settled in well, and have really cleared the brown hair algae that was on the rock. red and purple coralline algea are starting to show and ?grow.

My question is this. I got a yellow tang from a reputable regional coral and marine supplier that happens to be down the road. I quarantined him for 2 weeks. he ate all supplied nori daily, and swam about but didn't ever seem very curious. I put him in main tank yesterday. Immediately the fire shrimp jumped on his side and picked at his body - i (now i think mistakenly) thought they were cleaning him. This morning tang was stuck to the overflow box. I turned off pump, gently freed him, and then started cleaning up and re-establishing Q-tank. Within the hour, tang was dead and sinking, before I could get Q-tank running.

So, basically, anybody have an idea why tang died? I thought my tank seemed pretty stable. could it be the tank mates, and if so, do i need to get rid of the shrimp before i get another fish? could it be a poor tang to start with, but didn't a 2 week Q-tank run help this?

thanks in advance

I am reaslly sorry for your loss..
Are your water parameters(ph, sg, temp, etc..) the same as your QT tank?
The stress of moving a fish from one tank to another is highly stressful in itself, but then being put into water that is not of the same makeup of the QT water will certainly cause much more stress..
