I'm sorry to say, mate, but I think you are not well stocked, there. Rasboras and tetras (do you mean zebra danios?) need to in schools of at least 5, preferrably 6+. Having just a couple is not good, and even 4 isn't ideal. To fully boost your schools to what they need to be would overstock you even more than you already are, though.
If those are zebra danios, they need a larger tank than ten gallons, ideally, as they are extremely active fish. I would strongly suggest rehoming them and getting an extra rasbora instead.
