Try not to take the comments so personally. People are jerks. I don’t know how old you are but I’m guessing pretty young. Fish keeping is not as easy as it seems, and even people who have been in the hobby for 40 years make mistakes. Don’t take criticism as a personal attack - read and consider the advice because there is a reason you hear repeated advice. I don’t know how big your tank is but you probably do need a bigger tank. But your fish look well cared for.

When I was 15, I went out and bought a betta and put him in a little 1.5g aquarium that I thought looked cool. Didn’t know any better. Poor thing lived for 2 years. I wish I had someone to tell me what I was doing was cruel, I really do.
