man, i must of jinxed myself. i should of just left my tank alone but i had to start adding some calcium(which may or may not have done any damage) but i woke up sunday morning and noticed my hippo tang just hanging out on the bottom of the tank. 2 hours later i notice him on his side breathing hard. a lil while later he was deader than a doornail. then i notice that my flamingo snails like xenia and they ate all of it, they did it so quick. i think i might get rid of them and get some more xenia. hmmmm...what else..oh yeah...i just got done posting last week that i thought KRAZY K's clam looked cool and that i wish i had gotten that color instead of the usual blueish purple colored one..well, all of a sudden i noticed saturday that my clam was dying...all thats left now is an empty shell. my tank is falling apart!!!!

What are your parameters? Are you doing anything different than normal?

[ReefKing24]

hey man clams are calcium hogs and you need to add calcium a few times a week depending on the rest of your coral load. I add 20 ML. every 3 days. That isn't why your hippo died, how long have you been doing this? Everyone has to it seems learn the hard way first in this hobby, sorry if its just bad luck normally newer tanks go haywire if you start adding to much to soon.

Calcium would not have killed your fish in this case.

i am leaning toward a condition that happens at night time. Due to depleted oxygenated water Tangs will succumb to a low oxygen content in the water. Make sure you are aerating your water well? What kind of skimmer do you use?

Also how long have you had this tang for?

how big is your tank? what are all your parameters? how long have you had the tang? what other fish are in the tank? do you have algae for him to graze on?
