Marinebiologist, am I correct in guessing your 'unknown' barbs are Puntius arulius? If so, these grow to 4 inches and need a 4-ft length of tank minimum. If not, please post pics.
Focus on the bottom. You have enough middle dwellers in your tank already. Increase filtration capacity as you add more fish.
