My fish are dead

[40g Nano]

I don’t know what happened

 

[40g Nano]

I just want to take down my tank and stop

 

[Jon Fishman]

Not a lot to go on there. If it doesn’t make you happy, take it down

 

[alain Bouchard]

if you want help trying to find the cause, we will need a bit more info. But sorry for your fishes.

 

[40g Nano]

All of them were fine yesterday(clownfish and sailfin tang) I cleaned the tank and they didn’t seem too stressed them I dosed calcium.
I woke up this morning and they are all dead.
Tank is about 6 months old. All inverts are doing fine.

ca 420
Ammonia 0
Nitrite 0
Nitrate 0
Ph 8

What's your tempature? Any sources of metal get in the tank? Heater is intact, no rust from anything with magnets?

Inverts alive makes me think oxygen..

Sorry for your loss.

Not sure if you have coral to absorb CA, but if you just changed warer, there was no need yet for addition of CA.
I assume water temperature of new water matched that if the tank Nd it was RO water and not tap from the sink?

Is it a 14g Nano?

 

[40g Nano]

Yes. I don’t have a heater because it is summer in fl where I live. I have a bunch of coral

 

[piranhaman00]

You have a sailfin tang in a 14, maybe take it offline and do some research and then come back when you know more about taking care of fish

 

[40g Nano]

It was a very small one and it was just in there for a few weeks. I have an upgrade for it. Don’t worry tang police

 

[Jon Fishman]

I would love to see a picture of this tank in its prime

It’s not about being tang police, it’s about common sense

 

[40g Nano]

It was still a baby though he had plenty of space and was eating well. I fed him sea veggies and mysis shrimp daily

 

[Flippers4pups]

Please keep comments civil. Thank you.

 

[40g Nano]

Here it is

 

[Jon Fishman]

I see a snail. Any other inverts etc survive? Was it just the two fish?

 

[40g Nano]

a few snails and some hermits
It was all of the fish

No inverts died

6-8 mos is the common loss timeframe for fish in most reefs that didn’t use a disease prevention protocol, very likely here. One or both fish dies, ammonia loops the system...

keep it going but with corals and re prep the tank for a couple clownfish after doing your disease preps seen in the fish disease forum stickies

those systems are meant to be stacked to the hilt in coral, and 1% use of fish after disease preps then you will have fun. Coral heavy, not fish heavy

 

[40g Nano]

What does that mean exactly
