Maybe this is what I should've posted to begin with and not the other. Everything in my aquarium details is in a 50 freshwater. My figure 8 is just about the age to move over to brackish conditions where I might be getting a second for mating. I've been doing the research on my arsenal and haven't had too much luck. My cory and pictus are definites for the brackish move. Which 3 more Cory's and couple more pics will be joining the mix. Labyrinth smooth skins are great in salinity. Plecos, maybe seeing they are everywhere? What are definites and no goes?
