HELP! All my tangs are DEAD!

[dj synystr]

last night i came home from the club and noticed my tangs were on the bottom of the tank floating upside down. all the other fish, inverts, and coral were fine. its 3 yellow tangs, one purple and one hippo. this morning i fouind them all dead being eaten by there tank mates. this is an establish mixed reef. all my water specs are ok, cal, trites, trates, ammonia, ph, alk, temp the whole nine. these i checked first. has this happened to anyone else. does anyone have ANY idea as to the cause. PLEASE HELP with any ideas. thanks.

Wow that sucks I would hate to come home from a gig and find the same .

How many other fish are still alive?>What size are the live fish?Maybe an algea bloom sucking oxygen out of the water or a power outage while you were gone?

 

[dj synystr]

all my other fish are fine, roughly about 9 other fish. no power outage, no algae bloom. live fish range from damsel to lion fish. but they are all smaller than the tangs.

I was gonna suggest o2 as my very fist thought as well. Often you will see tangs succumb first because they are adapted to areas where o2 is at absolute saturation. One of the reasons fish often die at night, lower o2 and higher co2, coupled with depressed ph in many instances.

What do you mean exactly when you say your params are "ok"? Numbers, please?

I would first look into ph and alk, testing ph at different points in your light cycle. Also clean pumps, make sure the skimmer is working optimally.

Sorry to hear about your fish

9 other living fish plus 5 dead tangs....What size tank is this?

 

[reefshadow]

That is alot of fish for a 125... but maybe they are small specimens?

 

[integlikewhoa]

Did you feed that night? Maybe an algae clip that the tangs ate?

 

[dj synystr]

here we go with the damn tang police. the tangs have been in there for a LONG time doing fine. the fish were all happy my bio load is FINE. i dont have the WALL O ROCK like most of you on here. i now notice my smaller niger trigger is acting funny as well.

as for levels in check as in

Ammonia ZERO
Nitrates ZERO
Phosphates ZERO
Ph 8.4
Calcium 430
Alk was in the NORMAL range
temp 86.7

 

[anthworks]

That's to many fish for a 125.

 

[dj synystr]

[violation] it wasnt because of the ammount of fish. if you people have nothign else to say other than about the ammount of fish then JUST DONT RESPOND!

temps a little high :eek1: 86?

 

[sttroyiii]

Your temp and pH look high. I think most people try to stay under 82 degrees and between 8.0-8.2. Just my two cents...

ok...


lets see if we can add something constructive..

As well dj synystr..

anyway i meant 76.6 sorry not 86 and no i didnt feed algae they were fed with there normal mixture as they always are. and i didnt know abrevaitions were against the rules.

 

[BryanJ]

Did you check the chords on all equipment to make sure they are in good condition and not putting electrical current in the tank?

 

[Rcarruth]

Dude, if you're doing stuff you shouldn't (and you are, that's too many fish) don't get mad when people call you on it. Just the fish you've identified by name (seven of your fourteen fish) here can reach a total length of SIX FEET by my count. Having or not having a wall of rock doesn't have anything to do with the problem.

The number of fish in there probably didn't result in your tangs dying but it is the most glaringly obvious PROBLEM. Don't expect people not to mention it.

 

[dj synystr]

ok well i have never seen a tang go over 5 inches in a tank and i have had mine for over 2 years and they were 4" at the most. why is it to many fish please tell me. because everyones answer always is bio laod and my bio laod is fine, all my equipment on my tank is rated for double my total volume. and the next response is always teratory. well ALL my tangs swam together and never were aggressive towards each other.

 

[reefshadow]

Yikes...

Anyhow, 5 tangs dying all together in a very short amount of time, no signs of illness, with parameters being "normal" would point to a drastic drop in o2, perhaps in ph as well. Just my opinion, based on sad experience.

Perhaps along with cleaning pumps/skimmer, optimizing flow, look at what kind of air ventilation you have in your home. Winter is often bad for higher co2, lower o2 because of poor ventilation. That can translate into an environment that is less than optimal for turbid reef fish, and can kill very quickly, precisely as you have described.

How is the trigger "acting funny?" in o2 starvation, you usually see listing, inactivity and gasping.

Good luck to ya'

ok im seeing all that. i noticed that were my kalk reactor goes to had some white residue in the sump area i am assuming from the kalk mixture. is the mixture too saturated, does this cause a rise in co2?
