well that was weird... I fed from that new purchased culture this morning... wow those suckers scattered FAST! I am used to them pretty much staying where I put them and some scattering. These guys hit the ground running and running fast. Poor frog got her workout this morning chasing them down and managed to get most of them I think, but this could pose a problem for getting too many in the enclosure that she doesn't find eventually.... though I guess on the flipside it would give her things to hunt throughout the day instead of her eating them all so quickly. They also seem ever so slightly larger.... but I had thought I noticed the flies getting slightly smaller towards the end of the other cultures' lives.
On another note though... this culture has a sort of sour smell, that I noticed when opening it. It doesn't smell "bad" or anything, just like maybe I am getting a sense of the media in there, which I hadn't before in the others. I tried to smell the older cultures to see if the same and it's at least very similar but the others do smell more old and gross. The smell reminds me of like pickled baby corns.... do you think that smell is just because of whatever they use for media? All three cultures are from the same company, same store.
