thanks! those fish have lots of common names, its Puntius denisonii. around here they go by roseline barbs/sharks, or torpedo barbs/sharks. as for ph, honestly i dont even know, i dont test the ph. doesnt really matter since co2-induced ph swings wong affect the fish in any wayLoubard;4371250;4371250 said:Love the jawning flying fox (?) picture! Neat looking tank anyway, will be interesting to see how it looks in one year. What's your ph with all that co2?
