a barracuda is cold blooded because all fish are cold blooded

You can definitely do that, but you haven't made it clear that you have cold water in the tank before. If you can keep the water temperature at 72 F, then you can keep both cold water fishes like gold fishes and non-aggressive community tropical fishes like gouramis, platys, mollies, algae eaters etc with gold fish.
because they have an instinct to tell them go under the sand or what ever is on the bottom .or to just go deeper under water.
Whether or not a tropical fish can survive in cloudy water depends on why the water is cloudy. If there has been a spike in ammonia or nitrates, it can be deadly to fish. Tropical species tend to be more sensitive to severe water changes than freshwater fish.
they have bluuber and when the water is clod thy leva.
they store water in their stems,forexample, cactus plant
Yes all fishes are cold blooded.
When water freezes especially in arctic and antarctic during winter, the fishes use the oxygen dissolved in the water for respiration and these fishes have anti- freeze in their bodies to prevent ther blood from freezing.
