Updated pics of the wolf. Sorry about the quality, i made them with my phone. He is now in my planted 300 gallon together with 7 Cariba's and all is going fine. He's eating out of my hand and my Cariba's wont come near him. He even swims between the Cariba's when they are eating. He rules the tank
Yes, they are piranha's. I friend of mine has a mala together with his huge Cariba's in a bit smaller tank so it definitely can work. The first 3 days i used a divider, then i released him. He attacked the Cariba's right away and claimed his territory. Now for about 2 weeks he is eating like a monster and is very active. He even swims between the Cariba's when they are eating to get a piece for himself
