Not enough Harlequin Rasboras in tank

[Melodyx7]

Hi, recently my mum got two Harlequin rasbora from our local petstore.
And of course, the rasbora's are meant to be in a larger school, so I went to the petstore to see if they had more but they said *might* get more in a month. I feel extremely bad for the two fish and I was wondering if there might be anything I can do to help them while we wait. (They're also the only fish in the 15g tank besides decors and live plants)

Don't worry too much Melody. As long as you keep their water clean with your weekly 25% - 50% water change and don't over feed them, your Rasporas should be fine. You might consider adding a few Cory Catfish as part of your cleanup crew.

Thank you! I'll do some research on the Cory's and see.
