This is a list of some fish beginners should definitely avoid getting. Requiring more advanced care and setups, these fish need lots of research and preferably some experience before being acquired.
Boxfish
Leopard Wrasses
Tilefish
Batfish
Frogfish/Anglerfish
Seahorses (Even though they are common in the hobby they really do require specific setups to thrive long-term)
Sharks
Stingrays
Large Triggers, Eels, and Rabbitfish/Lionfish
Moorish idol
Blue Spot Jawfish
There's a lot more where that came from, but I feel like most of these are fairly well known.
