Help my fish died!

[KentuckyKenny]

All of my fish have died in my 40 gal breeder. My snails and hermit crabs are ok. Tank parameters seem ok
Temp. 77.9
Ph 8.2
Salinity 1.024
Ammonia 2.0
Nitrite 0
Nitrate 0
Phosphorus 20
What do I do now? Start all over?

Ammonia is likely your problem- toxic to fish. How old is the tank? How recently did you add the fish?

you have ammonia, your tank isnt cycled....that could be why they died.

Need more information before jumping to any conclusions. How old is the tank? Cycled? Dates of fish being introduced?

 

[Sharkbait19]

Could be ammonia, but that positive reading could also be because of the fish dying and decomposing.
Did the fish look or act off before dying? How well was the water aerated? When was the most recent addition? Did all die at once or one after another? Were fish quarantined?

 

[DeniseAndy]

We need a lot more information. How old is your tank and how did you cycle it? Were the fish quarantined? How many fish, and what types of fish? What else is in the tank? How long were they in the tank? How were they introduced?

Tank is a year old and cycled

 

[KentuckyKenny]

Fish were introduced using the drip method. Livestock lost. Royal Gramma, 2 clowns, Coral Beauty, striped Angel, Pajama Cardinal, yellow Angel, and Damsel. Also lost an emerald crab

How long ago?

 

[KentuckyKenny]

Introduced over the last year . Last one about 6 weeks ago. Died about 3 weeks after introduction

 

[desertrat505]

My guess is dissolved O2 is the culprit, the fish sadly suffocated.

A year old tank should be stable.
I think your dealing with a parasite.
Did they just turn over and die or did they display any unusual behaviour before death.

What's your filtration like?

I will say 3 angels in a 40g is a bit much

Pictures of the tank/equipment would be a big help!

I don't know what a "striped" angel is, but it sounds like it may not even be a dwarf.

3 angels/40g = constant fighting = constant stress = increased susceptibility to any type of disease, including parasitic outbreak.

Something isn't adding up. The tank should be plenty stable. Stocking is heavy but nitrates and nitrites non-existent. Plus, that ammonia... Somehow the tank "un-cycled" itself. The tank crashed. The key is to figure out why before starting over. Do you dose anything? List of equipment running? Maintenance routine?

Sorry for your loss as well. It can be devastating and I hope we can help you get back on the right track.

Hate to say but a lot of fish quits soon and factoring in feeding, likely an ammonia and/or nitrate spike
Ammonia at 2.0 is already toxic and What test kits are you using ?

Pics of the tank ?

 

[damsels are not mean]

I don't think ammonia just materialized out of nowhere. Seems an unlikely culprit. There is no such thing as a tank "uncycling". Most likely the deaths caused a spike. But what caused the deaths? Was there a heat wave? Can you feel any tingling like electricity in the tank?

If something killed off the bacteria, that would “uncycle” the tank.

 

[Tamberav]

Need more info. Behavior before they died and how they looked. Did they all die at once overnight? Or was it one by one?

What test kit do you use?

For all we know ammonia is 2.0 from decaying bodies.
