that Jardini will do what they always when he gets a little bigger and start to chase your fish till they die of stress or get shredded and die of infection,your best bet is to keep him by himself eventually he will be a huge pain in the ass. I had one for three years he got about 26 inches long and he started going after silver arow.about 26 inches long,and then my red tail garami 23 inches long.Got rid of him he was a really nice yellow faze one,but it was to late for my silver,and I had a really big black in there two. My tank is a 420 gallon and that was not big enough for the other fish to stay out of his way.Hope you have better luck than me fair warning Noel
