I collected all of the/ 6 of them and got the achievement

I think the fish achievement may have some secret requirement. I tried doing it 3 times, I only got it on the 3rd try because i kept catching fish until the achievement popped up. I think i caught around 8 fishes

if you kill the fish with a skill, it still counts as if you caught it. just use zhongli e if u have him and bam done

about the fish, i didn't even collect them. i killed some when the fire barrel exploded and got the achievement

You just grab the fish.. its not difficult

I'm not sure why nobody is writing how to get the achievement. I can not even figure out how to fish in this hangout, nevermind catch a certain number of fish! Con someone say the steps please!

For the "You've Got to have reserves" achievement, I only collected 5 fishes and still got it.

For the "You've Got to Have Reserves" achievement, you have to collect all the fishes (7), not more than 3, as the article says.
