RE: mixed species tank

[Ken Laidlaw <kl@roe.ac.uk>]

There is no real answer to this as individual fish can differ.  I've seen
A.nijsseni males that would try and kill anything that moved and others that
wouldn't harm a fly.

If you have to mix fish in a tank (which I often do myself as I don't have
many tanks) then you just have to keep an eye on things and move out any
aggressor that is ruining the life of everyone else.  I've got a trio of
A.caetei in with some D.maculatus in a three foot tank at the moment without
problems.

In the examples below the fish are not look alikes and probably do not see
each other as a direct threat.  Things may change if you were to add another
male macmasteri or A.viejita or another closely related apisto.  So it is
probably a  good idea not to mix closely related species.

Ken.

I've been surprised at some of the tales of cross-species aggression. At the
moment I have a four foot tank with a pair of mcmasteri, a trio of
altispinosa, and a juvenile pair of checkerboards, along with marble
hatchets, pencil fish, rummy-nose tetras and ottos.
