Mind you, I've just seen KittyKat, in another thread, say that 60l is fine for a pair, so maybe you'd be ok after all (just goes to show; a lot of fishkeeping is a matter of opnion!)
What are the dimensions of the tank; maybe we should base it on that rather than volume as rams are a territorial little fish!
Personally I feel that it is fine for a pair, that is a pair and not two individuals. That is if I'm thinking of the right tank, it is a standard 60 litre right? 60*30*35cm?
