How often do you guys change your scape for cichlids? Do you change often to dilute aggressions and mix up territories or just let them figure it out with a set one? What do your Central American tanks look like?
My fish constantly push the substrate to the front glass, so when doing water changes i typically move stuff around. breeding is not a goal but rather an annoyance.
i do it when i shuffle fish between tanks, get bored or theres mulm build up. more for me than anything else
Changing the decor can help with territoriality /aggression in the very short term, but is not a good solution if you are having those issue, since the dominant fish tends to "figure it out" pretty quickly. I change my scape up over time just to keep the tank looking good and make it a bit more exciting for myself, or improve the tank for the fish with more cover etc.
