So we have a betta fish in our marine bio club at school who is sick. She was sick when we got her, and we thought it was dropsy at first so we treated with aquarium salt. We don't know much about what to do when a betta fish gets sick so we looked up different ways to treat dropsy and found that as one way. She's been like this for about a month now.
and we dont know what we should do. Please help.
