Thanks for these quick answers.
After reading your mails, I asked more my friend. I think it is a
problem of conductivity (too much difference). I told her to ask
Gilbert the hardness of his water.
The fact is that we bought some Hypseleotris compressa too. Mine are
brightly coloured and the male fight with energy with the first I had
(who cames from Johannes Graf). My friend has found yesterday her
two compressa on the floor. And in the week, she didn't see them.
Mine were after two days full coloured.
Anyway, I think that is the reason because all other facts are OK (20
mg NO3, 1 mg phosphate, 24 °c, one hour acclimatation, 1/2 hour
between Gilbert's fishroom and home, that isn't bad conditions). Ph
has fallen in this tank at 6.7 now ! So too soft water, I think
Many thanks for your help
Cheers
Christian
