Is water change always necessary?

[briard]

nah bruh, u gotta change dat water. fish ain't gonna tell u when it's bad till it's too late. my cichlids would riot if i skipped a week.

For real. My African Cichlids would lose their minds if I slacked off. High pH means no room for error.

yo, just do the changes. fish don't got a voice, so it's on us to keep their crib clean. simple as that.
