LR Hitchhiker

[das75]

Cycling my tank with LR and after a few days this started showing up, small clear jelly like body about 1/4" long with very fine filaments up to about 6". Filaments quickly retract when debris touches then. First there were a few on the end of some weeds, now spreading over LR and substrate.

Look for an image of a sessile ctenophore online, and see if it doesn't look familiar.
