Hello guys, I'm from Rio de Janeiro, Brazil. I have a 240l black water community tank, pH 6,6, setted up to dwarf cichlids. It's not a biotope aquarium, just a community tank with acid and soft water, and tea coloured with tannins. Actually, I have on it 1 Apistogramma cacatuoides orange, 2 Mikrogeophagus altispinosus, and 1 Dicrossus maculatus, and their tank mates. And, 2 Mikrogeophagus ramirezi, a normal one and a golden one, at a quarantine tank. I'm trying to find the different cichlids species in the shops and with regional breeders, but looks like I'll need to buy them on internet.
