how wide would the tank be with aros that is the main thing is how wide a tank is so you would have to get one thats wide enough for a ull grown aro to turn in (though it would take a little while for it to grow this big) n how big was the red devil you put in? as long as whatever you put in is too big to be eaten then it should be fine but you may one of those weird Os that is really aggressive so would have to put in other aggressive fish that are big enough so that they can stand up for themselves and then be left alone also it might help i before you put anything in the tank to move around any deco you have so that their territory is disrupted
oh and why are there two threads on this from you can the mods delete one of them or something because there is some advice on the other one for you as well
