Ruslan, which shop on pasar road? Lucky Star Trading?

My cultures... one is still going, but stopped being very productive. The culture not dense enough. There's still daphnia in there though. Maybe I don't feed it enough. Still too queasy to use faeces, but I suspect it's the best food for them. Another one in a smaller tank infected with hydra... grrr.. how the hell it got there I dunno. I notice quite a lot of other micro-organisms in there too. Lots of weird little things. One is a small black slug like thing sliding along the sides.. some thread thin worms. All sorts.
