I'm really struggling with keeping fish alive in my tropical 10g tank. I initially started my tank with 3 platys, a dwarf Gourami and 6 neons.
Since then, 4 months ago, all of them bar 1 platy have passed away. The strange thing is that the fry from what I believe is the platys are surviving fine as is a cory catfish I added after the initial few fish I initially purchased died.
I test my water weekly and it comes in constantly at 7.6PH, 0 Ammonia, 0 nitrites, 10-20ppm nitrates using API freshwater test kit. The temperature remains at a constant 26-28C and I do water changes once per week. The fish get fed flakes once per day and the lighting is on for approximately 10-12 hours.
I also examine all the dead fish for signs of white spots, ich etc but nothing. Something that is possible is that a few fish died but I never recovered them from the substrate as I couldn't see them, could It be they were diseased and the existing fish may have ate their decomposing bodies?
Is there any other suggestions anybody has? I do know the GH
of my water is quite high but aside from this I am perplexed. I have bought all my fish from the same LFS
, is it possible they could be of poor quality?
Thanks in advance for any help.
