I know I have the right bacteria.
Not only did I get Arag-Alive sand and bacteria-liquid-additive, but I see bubbles repeatedly appearing in the sand, even after I stir it up.
Maybe something's wrong.
But, nevertheless, I'll go get some LR rubble from the LFS tomorrow. After I'm done cycling, I'll use it in my amphipod culture.
Any other suggestions will be welcome.
EDIT: OMG, I'm watching a living striped worm feeding from the rock. Aren't these things called peanut worms? I've seen these in my tank before, but only dead ones. OMG, the first animal life in my tank!
EDIT: OMG, a second one. Maybe they weren't dead after all?
