Yeah Crocodiles and Alligators seem kinda like a good idea but its a horrible outcome when put in an exhibit together.

A piece of toast and a terminator.

So would a well-fed Tylosaurus have any interest attacking a school of Enchodus or should I stick with smaller fishes like herring or reef fish in a some reefs in the tank?

Maybe if the Tylo understood that he had a constant source of food and wouldn't have to work for it for instance by going for the Enchodus kinda like how sharks behave in tanks full of other fish, so I would say Yes it probably would be okay for a Tylo to be with a school of Enchodus.

Pretty sure Tylo would still try to feed on them. Think of it like keeping a Monitor lizard in an enclosure filled with mice. Even if the lizard is well fed it would still instinctively kill the mice. Also, reading the wiki page on enchodus says they were a prey species to some large predators so I wouldn't risk it.

I can tell from this you don't have any experience with monitor lizards.

Very few animals will continue eating let alone hunting when full or when accustomed to a regular feeding schedule. That's not to say you can keep monitors with mice but the real problem in that scenario is going to be panicked mice bothering or even attacking the lizard. Large lizards (including monitors) have been kept with varied success alongside birds, tortoises, less aggressive lizards, and even terrestrial crabs.

A mosasaur is better compared to a shark in terms of behavior anyway, since we have (limited) evidence supporting a mob hunting style similar to sharks rather than true pack hunting or planning which suggests a similar hunting behavior even in singular.

Sharks can be kept alongside virtually anything because they become very accustomed to regular feedings and become very docile in response. They are still large curious animals (prone to putting things within reach of their mouths), so don't keep them with anything that might try and defend itself in a way that could put the shark in danger or unintentionally spur the shark to attack, but a shark isn't going to mindlessly devour fish as it sees them.

Tylosaurus is a huge predator that could more or less kill anything if it really wanted to. What you mix them with is really dependent on the lore of the scenario.

Is this a world where extinct animals are just everywhere in the wild? Or is this more of a Jurassic Park scenario? If the latter you're probably better off mixing it with less expensive modern fish in case it gets bored and decides to chase something. Is this a large indoor concrete building with fabricated environments? Or is this a series of sea-pens where small fish can come and go as they please and large fish are easy to acquire? Can this facility afford to replace fish readily? In this Tylosaurus wild caught, or has it been bred in captivity and raised by humans? Is the tank naturalistic with reefs and hiding places or is it a giant pool to give the Tylosaurus more room?

Keeping any animals is a lot more situational than you guys are making it sound, and that goes triple for extinct animals when you're also juggling speculative behaviors.

I love this! I agree with you that the Tylo would behave more like a shark and there are totally a lot more variables to consider such as the exhibit and fish type. Its definitely a lot harder speculating combinations on existing animals and even more with pre-existing ones. I couldn't have said it better myself!

I don't see how my example equates to lack of experience. I'd say my example is more common sense if anything.

And why are sharks always the default comparison with large aquatic animals? Why not Orcas or other cetaceans? You can't really house those with fish w/o them eating or just killing them for sport.

But most animals don't kill for sport, they kill out of necessity.

Most =/= All. Several species have been documented killing w/o any form of gain. Otters and some seals are kind of notorious for that.

No good hero is a one-trick phony.

Seeing as mosasaurs were mostly likely warm blooded, neither monitor lizards nor sharks could be considered a good analogue. Tylosaurus was an active apex predator, I would be very cautious about putting prey-sized creatures in with it.

You said a monitor lizard would instinctively hunt mice forever, but that's wrong, provably. It isn't common sense because it's literally incorrect.

The reason you can't just toss a bunch of mice in with a monitor lizard is because the mice will freak the **** out and seriously injure the would be predator. Improper feeding has been the death of many reptiles snakes and monitors in particular.

Sharks aren't cold blooded in the same sense most reptiles are, most of them maintain warm blood temperatures constantly just like sea turtles and tuna. Additionally blood temperature has more or less no bearing on behavior, plenty of warm blooded animals are dedicated scavengers or ambush predators, and plenty of true cold blooded animals are hyper-active.

I already explained why sharks are the best analogue for mosasaurs, it has nothing to do with size. The best analogue would actually be reef sharks and oceanic sharks, so not even particularly large sharks.

I think it's fair to say that when in doubt, just do what you want. In almost all cases, we simply don't have enough information on the animals to come to a definite yes-or-no conclusion.

I think we can all agree on this conclusion! =D

I meant commons sense in the sense that no one should house monitors with a bunch of mice in any scenario. It's true that the monitor would be in more danger though, so thanks for the clarity on that.
