My tank now seems to be cycled, many thanks for all your help guys, what a great source of info. readings last night where ammonia 0, nitrite 0, nitrate 40ppm. I will monitor this for a week before putting more fish in but still have a few questions.
1. I have x4 Tiger Barbs and Im looking at increasing this to six, should I put the x2 Tigers in before looking at putting the x2 Opaline Gourami?
2. Do I do a water change before adding new fish?
3. Im looking at getting a Bristlenosed Pleco and maybe some cory, do you recommend getting some different food for them ie bottom feed as my barbs do seem to devour everything.
Many thanks again guys for all your help.
