Woken Up To Two Dead Bodies

[**sarahp**]

As title says really. Tested the water at 9pm last night - ammonia 0ppm nitrIte 0ppm. Water was a bit cloudy but the 2 common plecos have been aquascaping all day and I just assumed it was silt from the sand they had been throwing around

Anyway at 7am I had 2 dead bodies - one of my female opalines and one of my zebras

Tested the water immediately and got the following

Ammonia - 0ppm
NitrIte - 0ppm
NitrAte 40ppm
ph - 7.6
temp - 26 degrees

no other signs of illness or injusry or listlessness -

its a 440 litre tank been cycled and stocked for 4 weeks - no other casulaties prior to this

stocking levels

copper rasboras - 4
harlequin rasboras - 6
long finned zebra danios - 5
leopard danios - 4
golden longfinned zebras - 4
boesmani ranibows - 2
blue rainbows - 2
red-tailed banded rainbows - 2
opaline gourami - 1 (now)
sterbai corys - 10
trilineaus corys - 5
khulie loaches - 4
common plecs - 2 but not staying cos they were rescues

I have 8x filtration via 2 external filters and I do 40% w/c a week

So - have I done something wrong - or is it just one of those things?

ps - all fish are juveniles and apart fromt he plecs which are about 6/7 inches no fish is bigger than 2 inches

By the looks of your water readings and the stocking, I think it's just one of those things.

Could have been ill when you got them from the LFS or something like that

Maybe the female gourami got beat up by the male and died? Only suggestion I got sorry! x

Hi, sorry for your loss
I would say its just one of those things. Moving that number of fish in one go will always result in the odd casualty, and you have done well not to loose any up untill now. Just keep a vidgalent eye on them for the next few weeks, to make sure the two in one night is just coincidence.
