Critter ID

G'day All

I collected some strange critters, accidentally, when collecting my Moore river shrimp and was wondering if anybody knows what they are?

They have collected bits of wood and fashioned themselves some shells from them and seem to be pretty happy with that. If they are not a major predator of shrimp or fish i would like to put them in the natives tank.

Here is some photo's.

Caddis fly nymph would be my guess.

Yep looks like it is. Going to put them in the tank and let them hatch.Not sure if the perch will have a go at them but we will see.
