blackworms?i just went to petsmart today and looked thru all the live food they had, and all i seen was large mealworms, medium mealworms, bloodworms (which looked too big for the bettas?), and night crawlers in a fridge, and some kinda nasty things that looked like huge mealworms on a shelf. thats where i found the fruit flies. *luvmybeta*, sounds like you have fun gettin them out. lol. i bought the flies in a vial thats got a piece of foam snugged in the end, so that you can let air cirulate, but they don't get out. all i gotta do to get them out is slightly pull one side of the foam out and wait for a flie or 2 to come sneaking out. then it either crawls on my finger or on the end of the vial and i jus blow it into the water, or it jumps off and lands itself in the water. it's amusing watching the beta tear at them things.
