Translation of carnivore in Spanish

Will you be online in 1 hour? I saw your translations and had some comments: rainbow is it 'arco iris' or one word arcoisris? Usually all words appear lower case. Sometimes it is uppercase. It all depends.
The conjugations of verbs are the biggest problem for me. I have never studied Spanish in school, but visited evening classes instead. This year I want to take a full Spanish course.
Thank you for your answer, my English is not very good, but it should be fun to learn together, don't you think? Generally, studying alone is no fun at all. So how do we proceed? How's it going?
