I'm sold on blue dempseys now. I've talked to several people including those that have sold and kept them for years. I may keep 2 - 4 in a well-filtered 55 gallon tank. According to those I've spoken to, the less aggressive blue JD will do fine if kept with others of it's own kind. Like keeping most cichlids, individual fish act differently so I'll sell some if I have to if keeping them together doesn't work out. You actually have to worry about other fish hurting these guys more than what they will do to other fish. So I've decided just to keep blue jacks alone. Do you think they will do well in a bare-bottom tank? I'm gonna put some terra cotta pots and vases in there for cover but I was planning on leaving out a substrate b/c the tank is easier to clean and I was planning on keeping them much like one would keep discus, with several water changes a week and the whole deal. Maybe not as intense as discus though. My water is about 7.6-7.8 pH so I think I'm good there. It is fairly hard water too. Is CA cichlid salt from Seachem a good thing to use? Any thoughts and advice are welcome.
