Will it be ok to have to Aros in one tank

They will fight and your new tank is a bit small for 2 aros

It is incredible rare for someone to have 2 aros in one tank as they will just beat each other to death! Just keep to the one and that one will be happy.

well the only other choice is pretty much jst to keep my rtg in a 75 gal tank forever >.<

Is the chance for them not too fight, too little to be substancial?

How about you spend the money from the super red purchase and get a suitable sized tank instead? The current tank you're cycling won't be large enough for one aro, let alone two.

A 4x2x2 is a normal tank size in Asia with a 6x2x2 being conceded as a large tank but they are both to small for any aro in my eyes

Some people claim that if you have a large enough tank, you can have two aro's coexist, but imo its a crap shoot. It would depend on their personalities and subspecies. I had a friend who had a 12 inch silver and a 8 inch jardini in a 300 gallon. They didn't fight but occasionally the jardini would nip at the silver. One day he put the two fish in a 75 gallon with a divider, because he wanted to add sand to the tank floor. the jardini broke through the divider and must have gotten in a fight because it ended up with major tissue damage to its tail and started breathing heavily for 3 days until it died of its injuries and subsequent infection. The silver must have bitten it, although it had never shown aggression before...these were juveniles too, not adults. The point is that you never know what will happen. Some people will start a community of 5 or more aro's to reduce aggression early and eliminated established territories. Other's will reduce the water level to force the aro's to swim near each other or increase the water flow to keep the fish swimming instead of fighting. Sometimes adding other monster fish will help reduce aggression.

there is a very little chance that two aros could get along in the same tank, unless you bought them pair. You could try mixing it with silver, but both are better be introduced at the same time, like I did.

I house 2 Silver Aro's in a 180G. One is a little bigger than the other and they get along amazing. They swim side by side and often rub against each other.
