Hello guys! My 13 gallon tank had 4 guppies inside, 2 platies and I had more recently added 5 neon tetras. I’ve had the tank set up since January-February and the cycle had been complete.Three weeks ago I had to leave for one week, so I changed the water and fed them the day before. One week later I returned to find 2 of my guppies and 1 of my platies dead. The other fish looked fine and the ammonia was zero.The next day after that I had to leave again for another week. When I returned the other platy was dead as well. I changed the water and checked the paremeters and everything looks fine! I don’t understand what went wrong. On Tuesday I went and bought 3 new guppies since I was down to two. Yesterday I found one of the new guppies and one tetra dead. Ammonia was zero, nitrates around 40 and no nitrites. At first I believed it could have been aggression due to hunger maybe,even though one week isn’t that much to go unfed. But now this? I was feeding them everyday and they still died.Do you have any suggestions? It’s heartbreaking to just watch them die one by one.
P.S. The fish seemed completely healthy and lively before dying, at least the ones that died while I was present. In general from the beginning no fish seemed lethargic or sick looking.
