its risky could work a smaller parachromis would be great in that size tank very nice fish as far as the bichir goes it could work just make sure the bichir has a good hideing spot to eascape the parachromis if it gets aggressive
i wouldn't get a senegal there one of the smallist bichirs and ornate would be better mabye a delhezi there nice and pretty active
Sorry about that not sure what happened.I keep a palma bicher with my jag so far no prob. Just have plenty of hiding spots for your senegal. Good luck.
