changed water yesterday and washed sponge filter out with cold water from the tap which i hear is the cause of this......
i put in 10 new angel fish i bought yesterday from a lady who was selling them.
they looked nice and comfy in my tank (this was 4pm)
i didn't go to bed until 3am as i was watching a film with the gf - all the fish were happy and swimming and i didn't think where was any problems.....
i woke up at 10am - i saw 4 floating tetra's thinking oh no the angels have eaten them.......couldn't see any more ! i had 19 in there at 3am !!
i blamed it on the angel fish and was just writting a message to the lady i got it off before i took out my remaining for dead floating fish when i was looking at the tank and an angel fish just sunk to the bottom n landed on its side n flapped for a second or two before dying infront o my eyes - i scooped it out and put it in fresh warm water but no life....
i then come to the conclusion it wasn't the angel fish because when i went to scoop the angel out, i disturbed the water and the other fish i couldnt see came out behind ornaments and started floating.....
i scooped them all out = 19 tetra's plus the angel fish!
i did a 75% water change thinking it was the water that killed them
-
i just done some water tests
Ammonia = 0
PH = 7.2 (so i put some PH 7 in cos it detoxifies heavy metals and removes chlorine from the water change)
nitrite = 0
don't have a test for nitrate
it is now 4:30pm and this was 10:30pm when i did water change an they all seem fine just like 24 hours ago
do you think it was cos i washed the good bacteria out the filter or something else? theres no white spots or damage on any of the dead fish
