Since those fish you listed are small fish, it should not be a problem in that size tank.
However, you need to monitor the tank daily to keep track of its progress. If your bio-media is mature and efficient, it will be able to handle the bioload. In any case, small water changes will go a long way to keep the tank and fish thriving. You will need to have a reserve of aged water for the purpose. Be careful of using chemicals though, as they can kill the bacteria in the bio-media and thus upset the tank's ecological balance.
