Wild caught greens refusing to eat

[cckent]

Hello,
I got 3 wild caught greens. My pH is 5.7 to 6.2. My water is soft. It's been a week and they have not eaten. I have feed them blood worms. Beef heart, turkey heart, and flakes. But they refuse to eat. Does anyone have any suggestions? Thank you!

I have a few doubts so, I would recommend you to share a pic of them.
At pH 5.7 to 6.2 seems to be okay as reproduction is affected at pH levels below 5.0 and many species will leave the area ²¹.
They might refuse to eat then don't leave it too long take an advice expert.
