Are milkweed bugs safe for bettas to eat?

answer me

No idea. But, I wouldn't risk it since you never know what they've been exposed to.

Just a tip - sometimes it may take a couple hours (or days) for someone to respond to a post.

Just feed your betta a good quality pellet food and leave it at that.

I assume you are talking about the large milkweed bug? http://bugguide.net/node/view/504
(there are a few other "milkweed bug" subspecies, such as the "false milkweed bug")

I would assume it is NOT safe to feed your fish - as the milkweed plant is poisonous and the milkweed bug will eat the seeds of the milkweed plant.
(The milkweed plant is what the monarch caterpillar eats and grows up on; it does that specifically because it makes itself poisonous/distasteful to predators that would want to eat it.)
It could be assumed that the milkweed bug does the same.
