They are a fish that you have to try! I started with four two inch w/c juvies, brightly splashed with blue spots, I was sold (I'm a sucker for big dopey sa's). brought them home and tossed them in with some small Geos, Satanoperca and small Creni's. They very quickly outgrew the 70, I had to move them to a 150, with some 8-9" Creni. sp. "Venezuela" - I wasn't to happy, but, they needed the room to grow! I was pleasantly surprised to see the Uaru proceed to beat on the Venz for about 20 minutes, after the beating, all the fish got along perfectly, the pecking order seemingly set in stone. Once completely settled, the four fish started to pair off, turns out that they were two males and two females - what luck! They began spawning less than a year after I brought them home with me at about 7" total length, their spawns were every week, one pair on Monday and the other on Wednesday, I never did raise one fry, my water is much too hard and the eggs were never fertile.
In the end, I still regret getting rid of them, the guy I gave them to raised the first spawn he got from them (they missed a week in the cycle but got back on track the next) and flooded Winnipeg with Uaru fry! They are capable of holding their own with any tankmates that you throw at them, they eat EVERYTHING and are not any more demanding for water quality than any other SA cichlids and the personality is second to none among cichlids.
Thanks for reading, hope it wasn't too boring :lol:
