Emergency

[tom_os]

yesterday i did a weekly 40% water change but afterwards all my fish were weird.

the danios were right at th top with their heads touching the surface, the phantom tetras did it sometimes and the cories we just basically still all day.

today i did another water change thinking something in the water was effecting the fish. i then found 3 dead phantom tetras. and after bthe water change they are all still acting weird.

ammonia 0
nitrite 0
nitrate 0 (after waterchange)

stocking:
4 golden danios
now 2 phantom tetras
6 cories
1 pitbull pleco

can anyone help, i have had an air pump running all day and cleaned out all the filter

update: the tetras look at the end of their life, just floating in the current. the danios are gasping at the surface, even though the air pump is on.

all the fish are only 2/3 months old.

hows your surface agitation? you might not have enough o2 in the tank.

good luck

update. all tetras are now dead. one danio looks like he has had it, the others are still gasping

i have had an air pump on full power for 48 hours now.

i have cleaned all of the filter. i think i will just have to wait and see what happens

any chemicals added to the tank by accident? all hardware working properly? ring up your water board and ask them if theyve flushed the supply

 

[tom_os]

no chemicals. last thing was a pitbull pleco on thursday last week. everything is working fine
