Was hoping for some help/advice:
Tank details: approx 11 gallons, ammonia 0ppm, nitrites 0ppm, nitrates 10-20ppm, has been running for a year now
I had 3 male guppies and 1 female (inherited her from a friend), so was worried about the m:f ratio and added 3 females about 2 weeks ago, along with a bottle of tetra safestart to be on the safe side. Then added another 4 females and 2 males about 5 days ago (I know, a lot- I had a moral crisis in the fish shop and panic bought).
There are four plants growing, logs and a couple of hidey holes. I realise it was overstocked, but I am due to get a 40 gallon tank from my brother soon so thought I could safely rescue a few from the grips of the nasty fish man...
Anyway this morning I checked and could only see 7 fish out of the 13. Found one dead on the floor, one dead in the filter outflow, and after much hunting, 3 more dead in a 'channel' that allows for the filter wire in the back. I have an open topped internal filter, so it's possible the one inside jumped in (can't have got sucked in as the inlet is covered in nylon), but I suspect he was also caught in the channel and washed up and over. No idea about the one on the floor but it's also possible he befell the same fate.
Have checked the water again (API master test kit)- all fine- and I'm absolutely baffled as to how it could have happened to so many fish so suddenly. They were ALL males as well, no females- could that be relevant?
Please help- I feel awful for the poor little things!
