digging cichlids

  • We are currently upgrading MFK. thanks! -neo
All my SA and CA cichlids dig. Every water change I'm flattening out the gravel, but within an couple hours there are piles everywhere.
 
dose he just dig or actually bury himself?
 
well my friends convict actually buries himself in the gravel, like 1/2 of his body in and 1/2 sticking out
