Yes, rainbow fish are shoalers and there are several species. They are often called the 'hard water tetras'.

What do you mean by 'shoaling like tetras' btw? They need to be in a shoal but shoaling fish only do that tight grouping moving in unison thing when they feel threatened, the rest of the time they just float around doing their own thing but keeping their friends in sight just in case
