It depends on what's making it cloudy.
If it's white or whitish then it's most likely a bacterial bloom. This is normal in a newer aquarium, or when you make significant changes to an established aquarium. The bacteria grow like crazy until the food supply is exhausted, then they should become balanced and the cloud should go away. If it fails to go away you most likely do not have a stable system. Try feeding less or making fewer water changes.
If it's green then it's usually algae. Algae indicates and overabundance of nitrates. This means you need to change the water more often and/or feed less food.

Yes if you keep a shark in an aquarium it will not grow to its normal size. It will only grow to a size that it will be comfortable in the aquarium.
The choice is up to you. If you set up the aquarium as a vivarium for lizards why should it not be used to keep a lizard in.
There are a lot of different catfish that you can get for your home aquarium. Most of them stay small enough that they are easy to keep.
