Dragon goby with senegal bichir or africans

[Jacob._.merc]

I am looking to get a dragon goby for a 40 gallon tank. The tank already contains two peacocks and 2 mbunas a blood parrot and a callychthys cat.
I also have a Senegal bichir, about 6 inches in a 20 gallon. Which would it be better with?

Hey,
definitely with the bichir.
G.broussonnetii are almost blind and can't defend themselves.
DO NOT (!) keep it with cichlids!
Keep in mind that a single specimen will need a 50gal brackish tank!
They are great tankmates for Mollies, brackish gobies, morays and so on.

Would keep the dragon goby solo. Potential t-mates can be too aggressive as already mentioned.
