I have a 10 gallon tank, that began with 2 females and 2 males. Then ofcourse they had babies. We had no problem with the tank for years, no over crowding nothing. We raised the baby guppies for other people. About 2 weeks ago we bought two new guppies. a male and female. Also some ghost shrimp (5) and two swordtails ( a male and female) and put them in the guppy tank. After that our old guppies started dying. Then the shrimp, then the male swordtail and just yesterday the female. The new guppies are alive and well. With each day another guppie dies. The two original females and some of the adolecent guppies are gone now. The Ph is right. No ammonia. I have no clue about the nitrates. I dont know how to check that. They are not overfed. Some of the originals are still alive and well. Do you think it is over crowded? We've had over 20 adult guppies survive in a 10 gallon for years. Maybe the shrimp and swordtails need more space? I have one surviving Ghost shrimp and I put him in my goldfish tank. I hope it's not something bad or my goldfish may die. I posted earlier about my goldfish dying, but the other four are doing fine. Let me know if you have any ideas.
Thanks
