Hello,
i've got a 165L community tank. last year i got 10 mixed barbs and since then the fish have been dropping off one by one!
i change the water every 2 weeks and the water continually tests as ideal.
the affected fish (not just the barbs) suddenly looses losts of weight then turns belly up! i don't know what i'm doing wrong, i'm new to tropical fish keeping and have had the tank running for 10 months.
any help/advice would be greatly appreciated!
thanks

I'll move your thread to the Emergencies section where it will be seen by more of our members. In the meanwhile, it would help if you could give us as much information as possible about your water stats, temperature, frequency and amount of water changes, etc.
