My animal is the peacock bass and this is what it looks like now: Right now, the peacock bass is a colorful animal and they live in freshwater. They are very adventurous and do many things. This is a peacock bass 500 years later. The peacock bass is very different because it has become more camouflage and it has moved to saltwater so that it doesn’t die. The peacock bass has already changed a lot and another thing is how it has little black spots everywhere. This is a peacock bass 1000 years later and it has become very vicious and deadly. It has changed its appearance completely and it is now very intimidating. It can also live in saltwater and freshwater making it even better and more dangerous. Its eyes have changed to look more scary so that predators don’t try to kill it anymore.
