Sand

I have sand and the fish are landscaping it, should I leave it only or spread it out? They are digging so deep that the decorations are starting to fall over. What do you do? Leave it only or redo it?

What species of cichlid do you have? With some, you'll be resetting decor on a regular basis, may as well get used to it. Some keepers use aquarium silicon to adhere decor to the tank bottom before adding substrate, but larger cichlids like oscars and jaguars will eventually break it loose.

I have African cichlids in a 120 Gallon Tank, thanks for the info.
