Will a pair of A.hongsloi and a pair of A.nijsseni peacefully coexist in a 40ish US gal (rio 180) tank?
theres plenty of plants and bogwood, i can put in some small clay pots for caves too
Id imagine that they would be fine as long as there are two definitive territories for them. I would recommend adding two females per male with a seperate territory for each one.
Id imagine that it would work.
