My tank is a little over 200 litres and 4 ft long. Currently, I have Danios, Black Neons and Pentazona Barbs as mid and top level swimmers. Although they are fish that do shoal , they seldom do. I was told that if I put a larger fish in there, they may see it as a threat and cause them to shoal better. Is this the case?
If it is, I want to give it a go as
A.> I want one large fish in there but one that will fit comfortable within the tank and is happy being alone.
B.> Obviously needs to be non-aggressive as I' do not want my tetras and Barbs eaten!
Any advice anyone?
Thanks.
