Definitely not a Daphnia: Beastie in pouch

[Lynnzer]

I got a few pouches of daphnia (in pink water) at the weekend. I am using a pouch a day between my nano fish tanks and I took another out of the fridge today and met a strange fearsome looking beastie swimming along with the daphnia. The thing is, the daphnia were mostly docile due to be being in the fridge but this thing was as lively as a lop. I thought it was a tadpole at first then I put my glasses on.
So what is it? Can it be fed to my larger fish or should it be crushed or flushed.
Just a warning here though. Don't just dump the contents of these live feed bags into a tank without checking out who lives in them.

Almost looks like a stonefly...

Or maybe more like a mayfly larva...

 

[Lynnzer]

Yeah, I'd go with mayfly larvae as set out that one of these has only a single hook on each leg end. (foot perhaps?)
It seems they are eaten by birds, frogs, fish etc, but you know when something doesn't look particularly appetising and you back away from it? Well this beastie is not feeding any of my fish for sure.

Dragonfly - a predator. That said, their reputation is worse than their bite. I have brought them in with wild daphnia, but they didn't eat any fish before I caught them. They are capable, and should be released into water outside (I like dragon flies) if the source was local.

dragonfly or damselfy larvae. Remove it because they are predators and will eat anything they can catch.

BAD bug ! Kill it !

This is a damselfly nymph, smaller than the dragonfly nymphs, but just as predatory...

Not for the squeamish

For fry, anyway....

Maybe release it in a pond/lake insdead of killing it?

You know what.... ìm gonna let it live. Its ìn a jar with some of the expired daphnia for food. It'll be kind of interesting to watch it develop.
