Fly found in a t container. Can someone try and identify it please?

Sort of like a fungus gnat?

How long is it?

are they harmful to t's or are they the kind that want to feed on other things?

Don't think so. Apparently the larvae can feed on plant roots:

That eases my mind quite a bit. Thanks for the quick response. Just as I was feeling better about my new injured t, I saw one of those in the cage. Freaked me out!

Edit: Also thank you for the link. That was very good info.
