Yes, he's right. You might dig out your dead fish as well to keep your water parameters more stable. My guess is that the other specimens may be stressing as well. You may consider putting all your fish into qt for a while...just to watch them. Ditto on the more sand and rock. You should have 55 lbs of LR. Putting your fish into qt while you're cycling new LR will be beneficial to all.
