I have bought 25 neons two months ago. They where just fine, until 5 days ago, when I saw there were only 5 left (i didn't have very much time to look at the aquarium these days). Because I thought one big fish had eaten them, I had that big fish removed and bought 21 neon fish. Now, after 2 days I have 8 neon fish remaining. HEEELP PLEASE!

200l Aquarium
1 betta
4 Pterophyllum scalare (small)
3 Aymonieri gold
1 pleco (small)
2 dwarf puffer
3 pangassius sutchi (small)
2 thoracatum albino (very small)
2 snails
many plants All my fish are mostly juvenile and have no problems whatsoever)
Tetra food once a day, filter with carbon, changed 15% of the water 2 days ago

Please post all your fish's size accurately in centimeters. Your suspects are angelfish, dwarf puffers and ID sharks.

What are your water parameters?

I'm ready for the pressure.
The drama and the pleasure!
If there is one thing I want to see here, it's HUMOR.
I believe I can fly!
I believe I can touch the sky!
I think about it every night and day!
I stand in awe of my body.

dwarf puffers 0.5 cm :D
sharks 4 cm (i bought them 2 days ago... so they are out)
angelfish 2x6cm 2x4 cm

I forgot that I have a Golden African Clawed Frog. (4cm)

The neons are not that small (2-2.5cm)

I have a lid on my aquarium so jumping out of the aquarium is impossible
I only found 2 dead neons... The rest abducted by aliens...

Clawed frogs rapidly get bigger as they get bigger and better meals, and from previous experience I can tell you that your fish have probably become its dinner.

Edit: Forgot to mention the previous experience was hubby putting three guppies into a tank with an albino that wasn't much bigger than them. I soooo was not responsible for that one.

still 8 left...

changed 15% of the water, but I really don't think the water had something wrong...
A good sign though... no neon died yesterday...

I kept an eye on the aquarium, and nothing seims to be out of the ordinary... And I don't have any cats :))

Do you have a test kit?

If so, could you post exact readings for Ammonia, Nitrite and Nitrate please?

I'm by no means an expert, but from personal experience, neons disintegrate FAST when they die. My recent outbreak of Ich caused me to have to medicate the main tank, knowing I would lose my two neons from it. They went from swimming around one day, to being almost compeltely disintegrated on the fliter intake the next - and I watch my tank very closely. So could it be that they are dying but you aren't paying much attention to the tank so they are decomposing before you notice they are gone? Just throwing it out there!

It's really gross when you see them sticking out of the frogs mouth.
