On friday I was horrified to return home from work to discover a leak in my 3 month old tank. It was right in the bottom right corner so in order to fix I would have to empty it anyway so i decided to take it back- it really shouldnt leak after just 3 months. I took all my fish out and put them in my hospital tank which was filled with aqaurium water- took tank bank. filled new one with as much water i could save (about 50%) put the old gravel and ornaments back in and topped up with fresh water. I ran the tank with the filter and heater over night and put my fish back in. All my fish are back to normal, behaving as they did. All seem healthy a part from 1 platy with a little fungus which im treating (I guess got a little injured when I caught it her) All my fish that is apart from my bonze cory. He has stopped eating and darts around erratically whenever there is movement outside the tank. I thought it must be stressed but its been4 days and still hasnt settled and i havent seen him eat- just hides. He used to have another bronze who died a while back and im wondering if he's getting more stressed because I know they like to be with others. I also have two peppers, they seem fine. I did a water check yesterday and theyre all fine- nitrites and ammonia 0, nitrates 15. Anyone any advice? should I get some more Bronzes so he can be in a group again? Thanks in advance!
