Hi everyone,
So I decided to buy a fish tank about 6 weeks ago. I did the cycle and purchased 6 guppies, 2 weeks later. I then bought 4 platies and 3 small bristlenose the following week. Things then started to go downhill about 3 days after purchasing the platies and bristlenose. 1 guppy died, then a platy died the day after. They were both at the top of the tank with their mouths opening and closing at a rapid speed. I thought that these two must've been weak fish so I didn't change anything in the tank. Another 2 days went by and another guppy died. It was doing the same thing: opening and closing its mouth at a very fast rate on the surface of the tank. I got my mate over who tested the water for me. All was good except for the PH levels which were at 6.0. My mate said these were due to low oxygen levels in the tank, so, he let me borrow his aerator. We also put some coral bones in the back of the filter and put some "PH Up" in the tank as well. It has since been 3 days since this happened. Another guppy has died and one platy isn't looking too good. By the way, I have been feeding them once a day, and only today I fed them twice (with smaller food) and they all went berserk - even the sick platy. I have no idea what to do!!! Please help!
