Algae Wafer Question

So I have a 30 gal with some community fish along with 2 Nerite snails. I used to have a pleco and had a bunch of algae wafers, so I dropped one in the tank for the snails. Well 5 minutes later I come back to see all the fish (neon tetras, swordtail, even a few bettas) eating the wafer. I'm not sure if it's good or bad for them since it's not "their" food. They ate it all and have had no changes.

Any Thoughts?

Please help.

Thanks!

I didn't find the right solution from the Internet.
