It has been an EXTREMELY SAD Week!!! So many of my fish have died and i have no solid explination why!!


Ok so this is what happened up to the die off

Firstly I have been working on my plants... I have a 29 gallon high, with moderate amount of plants. I am trying the EI method... During the day my room is pretty dark so when i get home i add plant nutrients

DAILY:
5ml of potassium (flourish), 5ml Flourish Excel, 5ml Flourish nutrients

2 times a week
2.5ml Flourish Iron, 5ml Flourish Phosphorous (2times a week)

So around 8pm i turn my T5 bulbs on total 1600k, and a 20 watt bulb (so 3 bulbs) to when i wake up approx 6-7am (just fyi No "algae" growth so for you peeps thinking i must have some crazy algae problem from 10hrs light)

Been doing that routine for about 3 weeks now with no adverse effects... I also have a DIY yeast Co2 reactor about 1-2 bubbles a second.


*** Ok so this is when i feel it started

One day my filter had tilted back and was leaking I probably lost 10-15% of the water so i fixed the problem and i figured, well since im already there i may as well vacuum the sand/gravel/fluval plant substrate while changing about 50% of the water in the process. (The water I use is tap NYC water, which i let sit in a bucket for at least 2 days to a week if not longer with water conditioner and also nov aqua water conditioner, occasionally i add night out as well.) So I changed the water... (i notice no difference in fish behavior)

Halfway through the week one of my cory Jullili die, and maybe one of my German blue rams, and about 2 bamboo shrimp.

The first weekend after the water change i decide im going to add some more Fluval substrate to my tank approx 4 cups (i probably have about 3 inches of black sand mixed with some Fluval plant substrate, but i felt i didn't have a good enough mix.) I did not rinse the fluval substrate before adding it to the tank, however the way i added it i made sure to make very little dust clouding to the tank.

**** The Die Off
about every day after that fish started dying. First about 2 of my other german rams die, next the apistogramma cockatouidie male died, then the apistogramma macmasteri male, then some electric blue rams, then more german rams, then the macmasteri female died, then my hillstream loach died, and finially the 2nd of the cockatouidie females died...

None of the ammano shrimp, or Ataya shrimp died, and some of the bamboos stayed alive, most of the other corys seemed fine, the freshwater flounders seemed unaffected... My electric blue jack dempsy 3inch looks fine, my bachardi looks fine and all the snails look fine...

But about 1/2 of my tank has died off...

I tested the water myself, 0 ammonia, 0 nitrites, 6.6-6.8 Ph

I brought my water to my LFS to be tested by them as well
very little ammonia was found but there was some..., 0 nitrates and nitrites, and ph was about 6.6...



WHAT IS CAUSING MY FISH DEATH!?!??!?

PS> I noticed before the fish started dying every couple days i'd see a fish do a quick rub up against a rock, but they would do it only once and i'd rarely see the same fish doing it. (I have never seen an ICH spot on any of my fish)

I feed my fish a variety from spurlinia pleco discs, HQ flake food, Live black worms (probably more blood worms then any of the other foods), occasionally live brine shrimp
 
I forgot to add before the water change i had come across a small canister filter, made for I think a 20 gallon tank, that i added to my tank as a backup to the Aquaclear filter i already have on the tank...

Inside the canister filter i have a bag of Phos-Zorb, and the little ceramic rings in there that came with it...
 
I would bet the co2 reactor possibly malfunctioned and then sorted itself out, but killed fish in the process.
Maybe.
Possibly.
Idk really.

Sucks though. Biggest die off vie ever had was three damsels killed by my other damsel.
 
if at first you uprooted a lot of plants you introduced a lot of ammo into the water that was trapped in the sub/roots, maybe???

sorry to hear....GL
 
The only plants uprooted in the process was a very small amount of the small foreground plants, i forget exactly what they were called, they are similar in root structure and look like micro swords.... I couldn't imagine the small amount of plants releasing to much ammonia into the water...

:( every time i wake up and come home i look for dead fish now :( and usually i find one or a few :( SOOOOO SADDDD i take alot of time and effort hunting down not so easy to find fish, and to have them die, is very hard to find replacements...
 
how long have you had the setup running? then think of all the other things you did differently a week before the dieoff. Including touching chemicals and not washing your hands or adding things that you might have thought are harmless.

That's all i got...
 
The setup has been running for a while.... 6-8 months, the canister filter a couple weeks... As for not washing hands and touching things... I know its awful but never wash my hands... and i stick my grubby lil hands in the tank all the time, to remodel, to fix plants, to pick out floating things... and more recently with a pair of metal tongs to fish out dead things...

Thing is in the many months i stuck my hand in there to remodel there has been many times ive clouded the water remodeling and it has done no harm to any of the fish, hence why this time im so surprised fish started dying... I want to blame the Fluval substrate but i cant imagine how not washing it first would make that much of a difference, that fish that have been living perfectly fine in the tank for months and have doubled in size in my tank all of a sudden die from something so seemingly trivial...

Hence why i think there is some underlying culprit... Would the stuff in the canister filter be killing fish??
 
It could be the ebjd just because they can be fragile doesn't mean they can be in a peaceful aquarium setting ebjds can be aggressive how do u think jds and ebjds mate the liplock and test to see how strong their mate is so ebjds can be aggressive I would watch very closely do ur dead fish have ripped fins
