Fish died with mouth wide open

[kenzo]

any brudder encountered this phenomenon of fish dying with mouth wide open and protuding?

juz added a small cup of water from main tank to q tank and the q tank fishes started to swim upside down and gasp for air within 3 hours..

all mati with mouth wide open..

any personal experiences on this?

thanx in advance!

can see all the way to the gut.. *bleah..

all my anthias died this way...got something to say ...

seriously...how are your main tank fishes?? they are doing well? That's weird...what's the temp and size difference of the 2 tanks??

[CalciumReef]

Actually Quarantine tank should be seperated.Not even pour in water from other tank.Did you try testing the water in main tank and quarantine tank?

the 2 tanks parameters about the same except salinity.. main tank 1.022, q tank bot same water where fish was bot 1.017..

main tank anthias and chromis no problem.. dat's why added abit of main tank water to acclimatize q fish to main tank water..

can it be velvet? or juz simply due to salinity difference..?

bro deepblue.. how u manage to resolve this problem?

thanx.

Did u expose ur fish to ur TV while u are watching "The Ring"?

[RockyBoy]

That's something new........

Long shot doubt i am right but could it be lack of oxygen?

I ever encountered this while fishing, always happen to the baitfish i keep for use as livebaits, due to poor circulation(only got airpump) quite a few won't make it and end up like what you have.

thanx man..

but should not be coz all ok in q tank.. adding a small cup of main tank water shouldn't remove all the oxygen rite?

hmm.. rite now researching into swim bladder bacteria, judging from the speed of the deaths plus their upside down swimming..

*headache...

[alanseah]

but if it's because of the bateria how come your main tank dont have problem leh..????

[strat]

Just curious. Did you cycle your q-tank?

krkr.. dat's wat i want to know oso man..

does look like lack of oxygen hor..?

hmm..will try stronger aeration b4 adding any medication..

thanx for all the advise!

hi strat,

yes i did.. other batches no such problem..

the oni change i can tink of is that i moved the q tank to a different room, so maybe temperature went up..

will move back see if can solve the problem..

thanx again.

such a pity,dats a very nice anthia..all of my anthias that died,died the same way too...maybe roidan aka the anthia expert can share with us on the secret of keeping anthias successfully?either they dun eat or they hide all the time..havent seen 5 of my anthias for 3 days now..dunnoe if they are dead...if they are,i'd better prepare for a major tank crash....

[kenzo]

yep.. dat's why researching hard on how to keep them well..

now that u mention it.. tink it only happens to anthias that i buy..

other fish rarely die.. and wen they do, not in such a manner..

cheers man.

[moron_clown]

i think the basics are really a very very good skimmer,plus alot of care and attention.if i remember correctly,anthias need to be fed a few times everyday...and they DO shit a lot....and i mean ALOT

[roidan]

can be many reasons...but probably some gill infection/disease may be the cause...if u see it panting and staying at one corner of the tank lifeless, then probably going to be a goner soon...

how to keep them well? most web resources will say good currents....oxygen saturated waters....and plenty of feeding throughout the day....

[moron_clown]

at last he has spoken.Heed his advice and there shall be no more deaths.

god save my missing antias....

[roidan]

no lah...not an anthias expert...

just keep your water conditions tip top and not only anthias will thrive...everything else will be in place.....happy reefing

[moron_clown]

thank u veli much.may consider selling my anthias as work and schooling commitments dun allow me to feed them several time a day...real pity...really nice fishes..

[Tigger]

poor fish

[Strongbad]

My dispar anthias just died....exactly the same symptoms....mouth opened wide !!

[kenzo]

aramak another case of Open Mouth Mati..

care to share the details leading to the OMM so that we can pinpoint the problem together?

cheers.

[Strongbad]

hmmm....not sure what happened. It was swimming to and fro, eating happily, until one fine day, it hide behind the live rocks...and then it died.

The other fishes are doing fine.

Strange...

Perhaps it's poisoned? I have a small carpet anemone..
