You can give it a shot but pay attention to your bichir, like i said i had them in a 150g with lots of places, and greens will become aggresive if the space is to small.
Ive that combo in two tanks for over a year, one common in a 75 with larger natives, one albino in a 40 breeder with smaller sunnies and darters for about the same, No problems at all.
