Fishes die suddenly

[Joeteng]

I had 3 fishes die suddenly today. 2 dies yesterday. 1 die few day ago. They I suppose not attack by any fishes cos not really any body wound except when they die the fishes nibble on them. But they have one symptom which is the die with their month open wide. The fishes dead are fire gobies, royal gamma, goby, purple fire fishes. All are hardy fishes and have been eating well. My last fish die just mins ago and i see him till his last breath from healthy 30 mins ago. Can anyone help? What is wrong?

My water parameter is salinity 1.020, ph 8.2, ammonia 0, nitrite 0

[Joeteng]

This is how my fish look fresh out of the tank.

My fish die e same way. No visible injuries other then mouth wide open. Some of e reason i can tink off is not enough oxygen or water movement and temp issue. I dunno. Sori to hear ur losses bro. Maybe wat u can do now is to change water...

[Joeteng]

my water temperature is 27degree and nothing is visible with the water. weekly change of 20%. Shouldnt be lacking oxygen cos bigger fishes are doing fine.

[cool guy]

Then like my wife say... Inside e tank got ghost n e fish is scare to death... Ahakz... Jus kidding bro... Im myself also not sure of e reason y my fish die too... Guess we jus hav to move on bro...

[Joeteng]

Pm to u Liao! I guess it is cynide again!

[cool guy]

If cynide, then ther will be either black or red mark the stomach bro...

Royal Gamma died of cyanide. You will get scolding from Lemonlemon. Dun always put the blame on cyanide when a fish die. Especially when 1 by 1 follow. Better check your other fishes and monitor them closely.

Poisoning? Boxfishes, cucumber, sea apple, anemone? Your ammonia test kit expired already?

[Joeteng]

Today one more casualty! U mean test kits will expire?

[Joeteng]

All of those die with belly either red or brown. Any symptom of diseases?

[Joeteng]

[Underwater]

Have you added new fishes couple of days ago? If so, then could be spread of diseases or harmful bacteria.

[DUCADOS]

Sad to hear this...

It's best to buy fishes from reputable LFS...

Those that r not professional better dun try...

[Joeteng]

I recently did get some fishes but they are fine.

[Joeteng]

Can my test kits really give me wrong measurement? Can test kits expired? My cycling period should be over Liao cos almost 6 weeks already.

yes test kits can expire!!! Look at the expiration date on the boxes.

If it's one by one, then it's probably some sort of harmful bacteria intro into the tank by either a new fish OR is it from the water ? Do you make your own salt water or do you use NSW?

WHat's your nitrate level like?

Nothing to do with your water parameter.Bro, from the picture you have a very serious parasite in your tank. As you can see, it is internal. Better treat your other fishes or else you'll have more casualty. Better find some antibiotic medicine for treating internal parasite.

Good luck.

My nitrate is near zero. Not sure is it bcos my test kit expire. There is no expire date on the test kit. So I think it has no expired bah on this brand of test kit. I intro naturally seawater initially then recently switch back to me salt.

Any idea what kind of parasites? The belly is usually brown when they die.

I am not very sure what sort of internal parasite but best bet is to look for treatment for internal usage.

At least now it is getting better. Fishes are now stable and no fishes die. Hopefully the rest not get infected.

Best wishes to your remaining fishes bro. BTW, how many are left?
