I'd go ahead and remove it, make sure it's not a dragonfly nymph because those things will kill fish. It doesn't exactly look like one, but I'd still remove it since they look similar and it could also be predatory

it is not a dragonfly nymph due to the tail having three long strands where as a dragonfly nymph would have 3 little tail spikes.

Hey everybody.
We found some of those in the aquarium. What are they? Are they bad? Should we do something?

Thanks in advanceView attachment 438580View attachment 438581
What you have is an insect larva. It looks very similar to dragon fly larva. If it is dragon fly larva, it will grow fairly large and will eat small fish. I can't be 100 % sure it dragon fly or damsel fly larva, but that's what it's mandables look.

Flushing seems cruel, it would be better to kill it another way first. And I'm sorry if I was confusing, it's definitely not a dragonfly nymph, but I was concerned it was also predatory because they look similar

Open windows and whatnot. I have a broken window and I've ended up with some pretty weird larvae in mine. Just a single adult gets in and lays eggs, then bam you have hundreds.

Nope we feed with flages, pellets and worm cubes
Then it is likely something came in a window and laid eggs. Just pick them out with your fingers or a net and dispose of them. They are too complex of an organism to use a treatment to kill them off without killing the fish and poisoning the tank.

I'm surprised your fish didn't eat it. Even guppies and goldfish would go for that, normally, so I'm sure higher-up fish would also (as long as they are not bottom-feeding, algae-eating fish types)

As a lifelong fly fisherman, what you have there is some sort of mayfly or damselfly nymph. I lean damselfly due to the long antenna. It is 100% harmless. Your fish will probably like the free snacks.
