Minimum Aquarium Size: A tank of 900mm x 380mm x 300mm (36” x 15” x
12”) is suitable for the smaller species of these fish.
Even larger tanks are even better!
Temperature: 23o/28oC 73o/82oF. Some fluctuation is normal in nature.
Habitat: Gravel substrate with plenty of rocks.
Water Parameters: Medium to hard, neutral water is considered ideal for the
fish. Should be well filtered and remain 'sweet'.
Health: Not generally a problem. Damage caused by territorial disputes should
be carefully monitored and treated as necessary.
Diet: Most of these fishes should be considered as carnivores.
Some fish can be persuaded to accept special pelletised dried foods.
Plants: These fish will re arrange gravel and rocks to suit themselves, often
on a daily basis. Any plants will be uprooted continually.
Breeding Notes : Egg-depositors (often of very large number of eggs).
Strong parental care and vigorous defence of young.
Availability: Generally a good selection available of young fish.
This should be taken into account when stocking the tank –
remembering that they will grow! Overcrowding
will lead to territorial fighting.
