Me too. I'm looking into auto WC'rs for the tanks. You said something about taking the stock levels back, not sure where the post went though. I personally don't think it's too bad - 7 rays (orbignyis are a bit smaller as well), 7 dwarf plecos, an aro, 24 SDs, 2 pikes, 6-8 geos, 4 severums, 2 uarus. The SDs could be taken back a bit I think though, 24 full grown silver dollars is a lot. I want to replace the plecos with some kind of catfish known to be "Safer" with rays. I also want to add pbass but I don't know about them being too aggressive of feeders to be with the rays. They might pick off the silver dollars too, everything else would probably be fine though. I'd go with orinos and perhaps kelberis in this tank if I did go with them
