Would it be harmful/bad for the fish to like…try to completely replace a substrate for their tank? Esp if ur already gonna take them both out to rearrange shit and try to decrease aggression levels? Like if u have the filters already…idk like
Knife fish apparently do better on sand bc they like to like. Rest in it and I feel like Snowball, who is a big carp would do good on sand bc I see them do the same thing the goldfish do and like pick and forage in it so sand would be better for both of them, and then the gravel that’s in there currently is like. Frankly it seems impossible to clean like it’s just…Neverending dirt comes out…but that seems like the kind of thing u do when ur first setting up the tank and cycling it, and like it would be a pain to do ?
(I also wanna replace the substrate in my Crayfish tank bc it’s like….the same gravel and it’s kinda gross and full of dirt)
