I had 4 male guppies in a 26 ltr tank ( i know it is small but was panic buy to save death from beasts in other tank that turned on them one day)
All been fine to date.........ammonia 0
* * * * * * * * * * * * * * * * * *nitrIte 0
* * * * * * * * * * * * * * * * * *pH 7.6
* * * * * * * * * * * * * * * * * *nitrAte 4* * *test results from this morn when all seemed fine.
Went out, came back 2 hours later one dead! Others active. Did 20% water change
I now have* my fave( Billy) lying on the bottom looking as if he is trying to swim but can't get up!!*
No white spots, no sign of damage to him......
Any ideas? What could cause such a sudden death and ill health in another?
Other 2 still playing in bubbles!! If i can help Billy it would be great
