Hi Anna & welcome to Project Noah!
Shekainah has correctly identified this for you so you can go ahead & add the correct common & scientific names in edit. I have move this to the arthropods category for you.
As Liam has advised, you should create a separate spotting for the fish & then delete that photo from this spotting.
The butterfly is a monarch butterfly and the fish seem like goldfish...
Welcome to Project Noah! I suggest splitting the two photos into separate spotting so that they can be ID'd individually.
