This tank is going through cycling now you have your stock in the tank.
Please read up on the fish in cycle, you need to be doing 50% water changes daily I would say. Be prepared to potentially loose fish as the high amounts of ammo are dangerous at 1ppm. Ideally you need to try and keep them under 0.5ppm while the cycle is going on and the you will need to start watching the nitrites as the cycle progresses.
I would say you probably have another 4-6 weeks before the cycle competition.
