Neon tetras keep on disappearing

Hello, I have a 60 gallon tank with 3 angelfish 1 clown pleco did have 13 neon tetras but now only have 5. The water water parameters are fine as well so I highly doubt it's that. Anyways this just started happening and I've had the tank for 10 months now. And I feel like they always disappear during the night. I have 6 and then the next day when I wake up I have 5? All the fish are acting perfectly healthy and the neon tetras that are left look perfectly healthy to. I don't feel like it's the angelfish either because whenever I watch them they get along perfectly fine and my neons will swim right next to them. I don't know if they act different as soon as I leave and bully them but I'm extremely confused. The only thing that I can come up with is that my light is to bright and it's stressing them out. Someone please help me cause this is really stressing me out.

 

Something may be eating them that likes to feed nocturnally. Had some catfish that did that to my tetras back in the day. A snack is a snack, doesn't have much to do with whether they get along or not, more if they can be caught/ate.

The tetras could have died and the pleco clean up the body

True but I don't know how it died in the first place.

Due to mass production, neon tetras have pretty weak immune systems so that might be the explanation to the deaths. A lot of people on Fishlore and just in general struggle to keep their neon tetras alive.

 

When did you start losing them? If you kept them for 10 months, it may not be poor health. poor health/disease would have already wiped them out in my opinion. Do they get skinny, lose color or anything else? It is possible that angels will leave them alone at first but they become larger, they may change their mind. They may also leave them alone when they are zipping around but may sneak on them by the first lights of the day while they are still half asleep. Having said that I had good luck with healthy neons only a couple of times. Other times I also lost them one by one.

 

I have read that angelfish sometimes hunt and eat them at night. Are they full grown angels?

 

Ten months ago the angels were smaller & now they're big enough to eat the neons. I don't know if the neons are "smart" enough to figure out that the angels are now a threat. Either that, or you have a roommate with a bizarre sense of humor.

 

The fact that they are always disappearing overnight is very suspicious. The angelfish are definitely the main suspects. I also have neons with big angelfish, and so far none have gone missing. I keep counting them though!

I never saw my betta be overly aggressive, but he ended up killing two fish. So, even if I watch the tank, I don't see what happens when I'm not watching.

I still think it's the angels but I could be wrong.

I have given up on neons. We have one left of a school of 15 after 5 years.

Going to cardinals.

They are pretty much full grown but not quite.

 

Yes, if you have had them for 10 months they will be pretty big by now. It would probably be better to get some larger or deeper bodied tetras that will be safe from the angels. As the neons look healthy until their disappearance I am pretty sure the angels are guilty. At night the neons sleep so will be less wary and easier to hunt than during the day.
