I need to show all the ups AND the downs. Bummer as I said in the video because any animal that dies under your watch is horrid, but we pick ourselves up, learn and move on!

    I treated for ick ( cant remember which brand i used ), but had an oily film build up on everything about a week later despite me following the directions correctly and all my fish were at the top. It turned out that the medication reduced the oxygen in the tank so i immediately re-oxygenated the water which i believe saved my fish with the exception of a few. Might have been something similar and the fish that were left were to far gone.

    Either it was compromised immune systems or sensitivity to a possible pH swing which weakens fish and then again they become prone to diseases and infections. But seems that it was a bad batch but for these reasons its always veery important to drip acclimate fish as a habit. And never adjust the amount of water during water changes too drastically to maintain some stability.

No nips, no ick, ammonia and nitrites are 0, nitrates are less than 10ppm, no noticeable changes then a sudden death. Very disheartening, but glad I watched your video. I feel a bit less bad now.

    I had a bunch of fish die off from a hand sanitizer contamination, if you touched this tank first before others, the others may be fine, but you could have had the same incident I did. Theres a chemical in some hand sanitizers, Benzalkonium chloride, which is thought to be what killed mine off.

    Great video as always bro, thanks. It's refreshing to see someone showing the bad side of the hobby too, for a change. Mysterious deaths are just part of fishkeeping sometimes, but......I did make a couple of observations in your video that I thought I'd mention. I notice while you were pouring in the new water for the emergency water change that you poured it through your fingers. This is not good practice in my opinion. As a rule, hands should be kept out of aquarium water as much as possible. I'm sure you know that even the tiniest trace amount of a detergent etc is all it takes to poison a tank (especially one so small) and as careful as we try to be we can easily have a lapse and still have a trace of something on our hands. Not just detergents of course, but traces of many other dangerous substances can be still on our skin. Grooming products, ink, oils, cooking ingredients etc etc. My other observation is in the same vein. When you removed the new fish from the bag into the net and drained the water, you did it right down in the sink where the net was touching the sink. Again, only the tiniest trace of detergent or similar is needed to cause a disaster. I know because I have made similar mistakes in the past. I appreciate that the supplier was honest about the ich problems etc but you did say that you had treated it and it had cleared up. so if they looked fine visually then I don't think an illness or parasite was the cause of the deaths, especially all the fish and so quickly. I suspect a wee toxic incident. Anyway, there's my 2P's worth. Apologies if I was preaching to the choir. Be lucky.

    Videos like this are good. There are upsetting parts of the hobby and it's important to show that. Death is part of fishkeeping and sometimes you just don't know what did it. Probably some disease you couldn't see to know it needed treatment, it just happens. I've always had a bit of die off with little guys. Nanos often seem quite fragile in my experience. Luckily I've never had a whole batch go.

    MD, you shouldn't be draining the water and restart that tank, further investigation and testing should be done in order to find the answer. But since you already tested the water and it is perfect, then you should try putting the plants into another clean tank and test with a fish. But doing this you will have to sacrifice a few fish by testing the sand, air pump, etc - I am not sure is this a good idea but if you can find the cause, it would be a life changing for the hobbyist since most of us encounter such devastating event once a while. Thanks for sharing your ordeal too.

    This kind of videos is almost on all experienced fish keepers channel... They just don't know the answer why.... In my humble opinion its the substrate in a tiny glass tank which swings many parameters... Nature has 100% water change every second but in a closed tank its not.. So invisible bad things accumulate in substrate even though you clean it every week.. The water parameters can't stay stable as in a bare bottom tank bcoz the substrate interacts with old water every second and brings down ph gh etc.. Then the weekly water change changes it again even a tiny bit.. So there's always stress.. Bare bottom with lots of water changes will avoid sudden unexplainable deaths.. This is just my opinion...

    Hi MD, very sorry for your loss it's sad to see a whole tank die like that. If the fish were showing signs of ich/ick there isn't anything you could have done. The disease kills fish very quickly especially young ones like you had. Because the fish were so small they may not be able to handle the full dose of medication. Maybe if your next batch have ich you can try using the heat and salt method. I have heard people have good results with this method and don't have to use medication at all.
