Im planning on rearranging it when they get bigger to try and prevent that. My synodontis is good at picking up the uneaten food but he wont be small forever. I made the small caves to make them feel more safe and to help the pH
looks good!! these are the next fish I want to keep. you'd be surprised what difference it would make by covering that back pane up would do. go get some colored paper used for posters and see what it'd look like.
