Hi Peter, > I am going get a couple of dwarf cichlids, and I was wondering how > flowerpots is used as caves. > > Do I turn it up side down, and break a little of the rim, so the > cichlids can enter? Yes. Include some small gravel (or inert sand) in your tank as the fish like to dig a little inside the pot. > > Which size and type (material) of pot is the bedst? Red clay (terra cotta) are best. I like to use 4" saucers which are used for standing pots on. You can also use small pots (3" rim) and instead of the notch out of the rim you can increase the size of the drainage hole on the bottom for the fish to enter. > > Is it better to find rocks, and build the caves myself?
