Are this good algae for tangs?

[Azael]

Are this good algaes for tangs? I want to make diy frozen food and I want to know if I can use this in the mix. So far I only gave them nori algae. This mix is made from Ulva spp. (sea salad), Undaria pinnatifida (wakame) si Porphyra spp. (nori).

The algae species mentioned are suitable for fish. Details on what is added to seaweed in the package is more important than the seaweed itself.

Thank you!
I will look on the package in the store before buying it to see if they added something or not.
