I bought some live saltwater rotifers from my local fish store the other day . there is some kind of fluff looking stuff floating in the bottle. I'm wondering if this is normal or has it gone bad ?

I need to find some good plans on making a PVC overflow rather than an overflow box, so if anyone would like to share ideas and all

One of My perc jump out last night..they we're a mated pair..the female jumped out..if I buy a new one will they become a pair again given the new one will turn into a female..any thoughts
