I decided to give Magnacetus a try. It is really good for killing. It deals 2.5 offensive injury. It has grab aswell! And it's one of the heaviest fish with 30k weight. Its 9000 health and 425 base damage are great! Only bad thing is that it cannot chase long, has a VERY bad dart and is pretty slow.
