Hi all, yesterday I purchased my first Bichir, a 15cm Senegalus. When I introduced it to the tank, it would hide under the rockwork for a bit, swim around the tank, hide, swim around etc. Today, it has been really active, swimming all over the tank (5'x2'x2'), its head constantly skimming the surface and even taking gulps of air. Does it sound normal that it is this active? It just came as a bit of a surprise, as most of the Bichirs that I have seen in shops are lazy, and barely move at all.
