Oddball and African riverine fish keeper
Soft water, tank is 24" x 13" x 13"
Just a fraction over 54l then, to be honest you are almost certainly heavily overstocked already if you have the Panda Corydoras and Tiger Barbs in adequate numbers (6+) and Swordtails deserve at least a 3-foot tank given their ~12cm adult size in hard water.
I would personally call a 54l fully stocked with just 6-8 Panda Corydoras, ~24-32cm of adult fish.
