Help Asap!

[digitalsteve]

i need help asap!

my eel(whiteeyed moray has been doing great , very active agressive feeder etc . all of a sudden i come home today and he looks dead. i grabbed him out of the tank after making a bloody mess in the tank and low and behold he is still alive , so i put him in the sump and he seems to be doing a little better. the only change i have made was adding a rose lipped sand conch to stir up the sand bed

all of the parameters are within range

ph 8.1, temp 80, nitrates and nitrites are both zero and i didnt detect any ammonia.

i cant figure this out for the life of me...

my mandarin goby seems to be doing great , if not a little ****ed since i moved some rocks. all the crabs and such are normal


i did notice a little mucous coming form the conch could that be killing my eel?

i did lose a snowflake moray a few weeks ago for no explained reasons but the whiteeyed had been doing so well ......


i am at wits end here trying to figure this out


thanks guys

Steve
