i got a pair of blue rams a week ago, they are very happy and have coloured up loads since we got them. at first the didnt mind the corys but now in on section of the tank - which isnt very private but is near some flat slate - they have started to chase the corys off. they arent hurting them just moving them out the way. could they be getting ready to lay eggs? is there any other behaviour that i should look out for?
