Right now I have a juvenile black sea bass (C. striata) that I've had for about 8 months. She moved over from a smaller tank. Of course, she's very aggressive towards anything. I also have several local hermits, mummichog killies (F. heteroclitus) and a rock sea bass (C. philadelphica). I have easy access to the ocean (Charleston), so anything that doesn't work out can be immediately returned. I was thinking about a few juvenile spadefish, any of the smaller flatfish, pigfish, oyster toads, etc (and lots of local shrimp for my big girl to eat). Basically, I come across a lot of different species and I wanted to try a little mix and match. Right now Its aquascaped with some local rock I've collected. Just wondering if anyone had any specific species they really liked (maybe some that were very active swimmers). Also, I'm wondering if a protein skimmer will be necessary. So far, regular water changes have kept the nitrates under control. Cool websites, by the way.
