I have 15 gallons tank with 3 swordtails 1 ram molly and rosy barb 6 kuhlis which live under the gravel, I know i should have at least 6 of them, I once had them and they fin nipping to death. So what can I add next?
How many gallons is your barbs tank? Might buy one when its on sale.I agree, im afraid your tanks to small for the fish you already have. Mollies need a tank width of at least 90cm and Rosy barbs and swordtails need bigger.
You would be best with smaller livebeares such as guppies and endlers in a 15 gallon if you have hard water
