Not currently. They require specialized setups, since pretty well any mobile inverts and fish may become snacks, they are strong and smart enough to get out of a tank (including pushing off a top weighted down with bricks), and the natural life span for most species is 12-24 months--hard to have such a cool pet and have it die in such a short time span. As more and more are being aquacultured, it's easier to select species, so I might get another one down the line since I will be able to get a male, which do live longer.
Not sure if they are smart but discus will sit and watch you, and if they see you have a yellow ziplock bag they know it is frozen food time and freak out.
All my Cichlids are pretty smart.They all know when it's feeding time.I keep their pellets in a Ziplock storage container,and when I pull that out,they all get very excited. :dance2:
