I'm pretty upset right now so I'm sorry is this get's long and/or confusing but I'll try to have it make sense. I'm at a loss as to what happened and I'm extremely worried for my one surviving fish, so any help is very much appreciated.
Last night I went to bed around 3:30am, and before doing so checked on my boys in their divided 5.5 gal tank. The water was clear, their color was vibrant, and they were both very active, flaring at each other and even me. I actually had friends over and was telling them about how much I love my fish and how upset I would be if I lost them...
Well lo and behold I wake up at 1:30pm today, check on them, and the water is cloudy, my boy Chaos was lying on the bottom barely breathing(I thought he was dead) and my other Nen had wedged himself between the thermometer and divider towards the surface, huge silver stress marks across his face and body. I was shocked!
In my hurry to get the bad water out of there I didn't even think to check the water parameters, but when I had the day before it was under .25ppm ammonia, 0 nitrites, and about 10ppm nitrates. The water has been at a steady 80 degrees all week.
As soon as I noticed their condition I changed as much of the water as possible without having to move them, as I did my boy Nen swam around, but Chaos wouldn't move. Only 5 hours later and Chaos is now dead...
I have a theory, but I don't know how much it makes sense,
I had people over and was having a party, so the light in their tank was on a lot longer than it normally would be(five or six hours more), in the tank was two live plants, a broad leaf anubias and a sword anubias. When I was changing the water I noticed that two of the broad leafs leaves were brown and curling in on each other, and almost all of the sword leafs leaves were brown, limp, and slimy. A lot of it's roots were falling off as well. My thought is that the light being on so much killed the plants, and as they decayed the ammonia spiked and crashed the cycle and good bacteria.
If that is
the case, what should I be doing for my remaining betta? The stress stripes on his body are gone, but his face is still stripped and silver, and he is once again wedged between the thermometer and the divider. I tried to give him food, and while he swam up to it with interest, he quickly swam away again without eating.
I removed the sword anubias, and trimmed the dead leaves off of the broad leaf. The rest of the plant seems in good condition but I'm still wary. Should I be moving Nen out of the tank? Current parameters are under .25ppm ammonia, 0 nitries, and 0 nitrates. It is filtered, and had been cycled but now I'm not too sure of that...
On the other hand, could this have been the effect of some disease? It happened so fast, within 11 hours, it seems unbelievable but I just don't know.
I'm extremely worried about my Nen, he is still very inactive and I'm afraid I'm going to lose him too. I just want to know what went wrong so I know if it was a fault of mine or not. Chaos has been with me for almost a year and a half and I'm devastated he's gone. :(
