If it wanted to, it could. Easily, I’d imagine.
The big problem with hypothetical animal vs animal fights is that, most of the time, they’d just ignore or avoid each other.
Look up “bug fights” on youtube. Even in a tiny container, the critters from different habitats don’t recognize each other as prey or danger, and spend most of the time trying to escape. The fights between animals from the same habitat are over much more quickly.

Apex predators like sharks are even more cautious.
