saw your recent pictures of your 29; you have a good set up; and also read your posts of your plans. All looks good. I'm still sorry you didn't keep the orange con because it's pretty rare at least where i'm from. But, the thing you need to watch for is aggression, because you are keeping CA cichlids; which can be aggressive. Jack Dempsys and cons will get territorial, and fights may get serious. I know you have a senegal bichir (saw the recent pics, cute), and I have one as well. Believe me, mine went from your size to 5" in a few months. He (i'm guessing) is pretty mellow usually, but I did see him chasing my other cichlids around already, and senegals and all bichirs will grow to about a foot long. also, because right now, yours is just a baby, and probably shy and hiding all the time, make sure you feed him enough. That was my issue when I was caring for my bichir.
Just be observant, and very good job, and good luck to you.
