Personally I would do a water change after finding a dead fish anyway. Have you looked closely for signs of whitespot? It will look like tiny salt like white specks on them, and is easier to spot on tails and fins. My tank had a nasty case of whitespot and my glass catfish were amongst the first to die unfortunately.... get looking for spots!
Thanks for replying! That was quick!
Would a 1/2 water change do?
Nope no whitespot - the others look healthy and happy! Looked at the smallest loach and he seems to be struggling to breathe now too!
I've got a pH test kit but can't find the instructions and when I did find instructions on the internet on use they were in German
Give me the link, Ich spreche Deutch.

Excellent... I'll post it now - going to have to search for it again!
I speak Afrikaans which is close to Dutch and German but the translation is going slow as I've not spoken or read it in 5 years! Arrrrrrggggghhhhh!
Guess what Emma, Google now translates pages! Whoooohoooooo!
Our pH is fine too i think... is pH of 7 ok?
