Okay so i have a 3" payara (Hydrolycus Armatus I believe but the store I ordered it from could not provide the Sci. name) currently in a tank with 2 synodontis catfish and one albino bristel nose all three are less than 2.5", that all seem to be getting along good so far. I was wondering what other tankmates would be suitable and if the current ones could potentially end in disaster. Also, are there recomendations for what kind of scenery they like? Open spaces? Not to crowded? Plants?.. that sort of thing. Any comments would be appretiated! Did some research but open for any experienced opinion! Thanks!
