That's great. I think Jerry and myself understand the term now. Until I can filter the protozoa (or was it paramecium?) and the other delectable ciliates, flagellates, & maybe rotifers, from the crap...it will still be called "the crap released from squeezing the filter sponge. I think everyone gets that. So freezing looks like the way to go. I have had some problems with the apisto trader list & was wondering if it was only me. I am also building (or trying to build) some racks for multiple tanks..probably 20L. not a carpenter, not an engineer, just a scientist that likes to do that stuff. Does anyone have any advice besides the one in the Krib? I want to see the fish, so they won't be as spatially efficient. Also, is there any type of database around? maybe the ASG has one? it would be cool to have something easy to access the likes and dislikes of the different fish, but people wouldn't make as much money making books. Although, books are nice for reading anywhere...and they don't impair your vision like computers. just a suggestion/inquiry. ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
