Hi, Thanks but i think she's ok now i woke up this morning and saw her eagerly swimming up and down trying to chase the guppies i was so relieved

so i decided to let her explore her new tank and she's just gliding through the water so she's ok now but i have a question:
do i still keep feeding her peas or should a get her back on pellets? i'm using Hikari micro wafers but i don't know if i should change her diet because it's the same thing they use in the store and i don't think they're really qualified to be running a huge aquarium they always overcrowd intensely you can hardly see the fish so that's another question i don't want to be the bad guy but i was wondering if i report them is there an organization that will listen i know most of them pass it off as "their just fish" but all creatures are entitled to a good life anyway should i feed my betta peas or pellets? thanks
