Please get a bigger tank soon.This tank is only a short term solution as big tanks are quite expensive
How long have your fish stayed at 5cm? If it has been long you might think that "oh they are small fish so it is ok" but no. The only reason why they haven't grown bigger is because they can't. They have so little space that their brain tells their skin to stop growing. However their organs will keep growing. There will come a day when the organs are too big to by held in my the morbidly stretched skin and the fish will die.
