I had a look at the pictures but the ficus trees seem to have a denser foilage than that compared to my tree. Pictures of ficus in the internet also shows they have arial roots which isn't present in the bonsai that I have.
But I did snip of a leaf and there was a white extract that oozed out.
After hearing the confirmation of the latex, the fact that it was purchased at Ikea and the thoughts of the other members here I am all but certain that it is indeed a Ficus.
Pictures of fig bonsais seem to look very similar to pictures of my bonsai so could it be a fig tree? Unless the ficus is the scientific name of fig?! I'm probably coming off as highly ignorant, I'm so sorry.
You are correct, the tree known as Fig is a type of Ficus.
Pictures of ficus in the internet also shows they have arial roots which isn't present in the bonsai that I have.
High humidity is required to encourage aerial roots to grow. Also. I'm not sure if every species is equally capable of forming them.
Even this is being called a ficus?!
As Big Vine noted Ficus is a large Genus with many variations. The Ficus in this picture is one of the better ones for bonsai. Look up 'Willow Leaf Ficus'
Unfortunately the tree was bought from ikea where the salesman didn't seem to know a lot about bonsais.
Also we were given a spray bottle and asked to water the plant using only the spray so is that how it should be done?
No, that is bad advice. I would suggest that you soak your tree in a basin of water for about 10 minutes until the soil is saturated. I don't do this as a matter of routine but the soil looks a bit dry and considering the advice you were given, it certainly will not hurt.
