i have had my red tailed payaras kill my juruense and a jurapari recently and was wondering if a six inch pictus and jaguar cat would be okay or a tiger shovelnose as bottom dwellers?the tats usually ignore everything else but the juruense was territorial and got in a fight with them over night.they are still with a yellowtail cuda and three massive silver dollars and a spotted silverdollar and so far no more problems
