Re: [Killietalk] What are these?

[Robert Toland <morgrid at comcast_net>]

They look like caddis fly larvae to me. I often find them in trout streams and I know them by the cocoon they build from silk they make. Fly fishermen imitate the adult forms, and when the hatch is on it is a pretty exciting time. There are apparently over 1000 species so I can't give you a more precise answer than that.

They're up to half an inch long, red segmented worms that build debris   tunnels around themselves and mostly look like strands of fish poop,   unless stirred around to disrupt their cover as I've done here, to   photograph and identify them:

They have again appeared in my indoor daphnia cultures, started from   moina purchased from Dallas discus, which definitely didn't contain   anything like this when emptied into the trays. 
So they're either being started by something inside the house laying   eggs in the water (if so, these have grown to this size in less than a   week), or are coming in from the used tank water I used to dilute and   fill the trays (water scooped straight from a healthy planted tank   with fish).
