This triggerfish is territorial and will protect his place in the tank. It should not be in one tank with smaller fish or invertebrates, otherwise triggerfish will eat them. The best is to have this fish in a fish-only tank. However, if you want to keep this fish with other fishes, you should have a large aquarium and tank mates should be large fish too. Blue line Trigger needs to have in his tank rocks and corrals, but also sand. He use to search for food in the sand during the day, and in the evening it searches for a safe place for sleeping in the rocks. You also should be careful with placing those rocks, because this fish like to replace rocks just like it wants.

When it comes to food, this fish is a carnivore, so you should feed this fish meaty food, such as fish meat, squid meat, crab meat. You should also give them crustaceans, because the hard shell helps its teeth to stay in good conditions. Pseudobalistes fuscus should be kept by experienced aquarists.
