I bought a pair of adult German Blue Rams yesterday, a little unplanned but I'm not short of tank space at the moment (or at least wasn't before a trip to the LFS). Currently they are in a tank with some Ember Tetras but I've seen something online that said the GBR's will be too aggressive for the tetras. So far they've not bothered them at all but I guess it's early days. Should I move the Embers? If so, what might be suitable companions? There are corys and twig fish in there too but I gather they are not a problem.
