Hello!
Now it seems that my hydra are gone! (this time with flubenol 😉 )
This morning I made a water change in my P. phoenicurus tank, this evening I will do in my still not really black water 100l tank. The 100l tank (with just 60 l Water) has also shrimps as inhabitants and bladder snails. Both species seem not to be disturbed by the flubenol till now, but the hydras have vanished….
