I 99% agree. But ive seen the odd thing happen before in tanks. Lol. As long as you keep an eye on aggression then your doing your due diligence. And good luck. I had a good friend that kept a dozen pirahna in a 300gl tank. One of them being a german black rahm. I dont know much abt pirahna, but hear the german rahms are more aggresive than reg pirahna. Anyways after 2 yrs of feeding them feeder goldfish. And them gobbling them up like war machines. They let one live, it grew to get pretty big over the years. Hung out in the group occasionaly, swam, and ate freely. He wound up givin it to his moms goldfish pond after a few yrs. Pirahna Kept destroying every other goldfish he put/puts in. Point being, sometimes a cat and a dog do ok together for some reason.
