I just found this purple worm/caterpillar in my fish tank. Also, one of my ghost shrimp was attempting to eat it when I found it. I have no idea where it could have come from... Can someone help me identify it? Also, it's around an inch long...
i saw some of those at a pet shop recently. they said they were hornworms. meant for feeding large lizards. the ones i saw were a blue / light blue / teal kind of color, but they were very similar to the one you posted.
could have hitched a ride from the petshop via some new driftwood or plants maybe (???)
Thanks, although I sort of doubt that it hitched a ride recently. This is because I haven't put anything new into my fish tank for the last couple of months. (I haven't been to the pet store since January.)
But maybe it is one of those hornworms... however, I don't see any horns.
