Hello,
Though I am not all that familiar with your bichir...I do know
that these two types of fish really dont mix.
The most obvious reason IMO is that bichir's diet and
environment for housing are quite different.
The bichir's eat mostly protien in the forms of meat and other fish
and Mbunas such as your kenyi are vegetarians, and eat mostly
algae and sprilina flakes along with veggies.
As for housing, bichir's are used to a softer water with lots
of plants and drift woods for comfort, Mbunas on the other
hand like the water very hard with a rocky terrain for hidey
holes.
So, again these are only points of concern, you can house
any fish you want together in what ever sized tank you like.
But, if you are interested about the long term, your tank
whichever fish you decide to keep, is too small for either,
esp. the bichir, they require lots of space to roam and get pretty large on their own. Kenyis though not a large fish, are very
active and quite aggressive and like to chase each other around.
I have kept African cichlids for quite awhile now, and have had
my share of good and bad as with anyone keeping fish, but I
decided to go with a species only tank when looking to breed and
keep kenyis aka Ps./Met. lombardoi, they are just down right nasty when housed together with any other Mbuna.
Good luck with your fish, ciao for now, FG.
