This is purely for my own knowledge, i have no intention on acting on my ambitions until i am thoroughly educated. I have seen many pictures of festae pairs and have fallen in love with them. I would really really like to get a pair but don't know too much about them. What size tank should i be looking at, should i get any tank mates for them and what kind, what substrate and rocks should i get. I know they r very aggressive and would be perfectly fine with them being the only fish in the tank. Also what filtration will be suitable and any other information will be greatly appreciated. thanks
