Hi, i added an electric blue ram male to my 20g yesterday and what i thought was a female (i think its a male now) electric blue ram into the tank today. I am going on vacation tomorrow and will return late sunday, will these 2 male rams be ok in my tank? Or will they fight to the death? They seem to be challenging each other right now, nothing bad, just flaring their fins and the occasional ram/nip. What should i do? Help please!
