Thanks Zoddyzod, so what you are saying is that I can add those fish to the ones I already have in my tank? I have about 1.5 - 2 inches of sand substrate in my tank.
I recently cycled my new tank which is a quite tall 3ft which holds around 48 gallons. So far I have a couple of peices of nice driftwood with plenty of hiding spots, a hollow rock, and a few anubius and amazon sword plants and sand. I have put in ten harlequin rasboras and one bristlenose...
