| This substrate sifting cichlid is a good candidate for stocking in mildly aggressive, community tanks. Mature males will show a bit more blue 'spangling' iridescence than the females, and have longer, trailing anal and dorsal fins. Keep individuals or established/compatible pairs of the Blue Sifter in the aquarium. Sand substrates will certainly be appreciated. Be careful - this cichlid does NOT tolerate other, non-paired members of it's own species very well, unless stocked in very large, 300 gallon (or larger) sized tanks. |
