Apistogramma borelli ‘Opal’Easier to socialise than for many other dwarf cichlids, the umbrella cichlid is considered as relatively peaceful but can be aggressive at times especially with smaller aquariums, the company should rather stay in the middle or upper levels of water levels. An excellent pet for a planted aquarium but it also needs a fair amount of open space. This cichlid is generally compatible with other peaceful fish as long as it has plenty of space.
