shit, dead fish:(

[GlitterySkulls]

just found the black moor & the fantail dead, one on the top of the filter, one stuck to the side :(

both fish were fine last night, swimming about happily. no signs of disease, tank in fine, clean condition.

the 3 zebra danios are fine

i've removed the bodies (the black moor had goldy-coloured patches shining through its black) & i know i'll have to clean the tank out once dh comes home, but i'm totally about this, they were fine until i found them dead!!

has anyone got any ideas what this could be?

yes, at least three times.

i know the tank is less than ideal, but it was my emergency back up tank- my main one was goosed- and it's no longer overstocked, its just two lonely looking wee danios :(
