Overnight death

Ok I have a hundred gallon setup for tetras and other community fish. During the day the fish are active and healthy, but at night I tend to find 1 or more swimming perilously in the tank. I also have a relitively large pleco about 8 or 9" in the tank. I was wondering if he could be the culprit. I figured most of the tetras go domn to the bottom and enter a sleep like state and the pleco is just getting started. Could he be stumbling across these tetras and damaging them. Some disapear and some I find in the tank dead?

Thanks for your Time,

there appears to be a virus that some tetras such as neons are prone to. It is said that it is untreatable and can be transmitted to some community fish. The cardinal tetras do not appear to be affected by this virus sometimes called neon tetra disease. If the tetras you speak of are not neons then much more info would be needed . See the notice at top of freshwater emergencies and disease section.

The most important medication in your fish medicine cabinet is.. Clean water.

Can you tell us exactly how many of each species of fish you have? What is your water change routine, how much do you feed, and what exactly are your readings for ammonia, nitrite and nitrate?

are all of the different types of tetras being affected?

I dream of a better tomorrow, where chickens can cross the road and not have their motives questioned.....Dont worry about what people think, because they seldom do.......If you cant laugh at yourself I'll be glad to do it for you.....stop trying to impress people, they're too busy trying to impress everyone else to notice

Yeah and it seems to only be happening after the lights go out, there isn't any severe temperature drop. It isn't the sudden shutoff of the lights either.

Ok new data. I am ruling out pleco. I have discovered two tetras today finally get a look at what is going on. A neon and a glowlight seem to have something growing on or near there head. The neon has a sort of white substance growing behind it's head it kind of looks like a scar. Its head looks a little swollen as well. The glowlight has something on top of its head that kind of looks like a mohawk. I noticed that they will stay stationary because if they start swimming they lose control! Any ideas? If so what should I treet it with? This is very frustrating.

Thank you

What kind of pleco is he? Most are vegetarians, and unless he is not being fed well enough, the larger varietys will feed on fish's slime coat.
