I have pets. They are goldfish. Their names are Crash and Sin. They two years. They live in a large aquarium. There is an aquarium on a table near the window in my room. I feed them a special food every day. They can swim well, but they could not speak. I like to watch the fish swimming in an aquarium.
У меня есть домашние питомцы. Это  золотые рыбки.   Их зовут  Краш и Син. Им два года . Они живут в большом аквариуме.  аквариум находится на столе около окна в  моей комнате. Я кормлю их  специальной едой каждый день. Они умеют хорошо плавать, но они не умеют говорить. Мне нравится наблюдать за рыбками плавающими в аквариуме.
