My fish liked almost any frozen food...especially the blood worms but then I got a bad batch & lost most of my fish including my green tiger barbs. I was really upset about losing them.
I threw out the remaining ones ( a large package at that...cost me something like $15 to $25).
A few weeks later I went back to the same store I'd purchased. They told me had I saved the rest of them & receipt they would have given me a refund...why would I save worms that had killed my fish???
They had become unthawed sometime between shipping & the time I purchased them & then re-frozen...really sad to lose so many fish at one time.
I won't buy frozen blood worms any longer.
And I never went back to that store again.
You have to be careful with frozen foods unless you make your own.
