I've had a Thai silk FH living with a red devil in the same tank for a while and I've had no issues with aggression. If I were to put them both in a 75G do you think they can live together? Keep in mind they've been together since baby's

The questions are what size tank are they in now, how old/big are they, and what gender?

If they're smaller fish growing up together you may see a whole different dynamic once adult hormones kick in-- it's a mistake to think because juvenile cichlids get along peacefully they'll always get along. If it's male/female or two females it's possible they'll work out, but no guarantee. If it's two males you definitely don't want to be putting them in a smaller tank-- if that's the deal. Putting them into a larger tank might be ok or maybe ok for a while if they're still growing. Then again, it might give them just enough territory to fight over. The thing is they can vary by age, gender, size, circumstances in their tank, changes in tank-- and by individual fish. Makes these kind of situations hard to predict.
 
They are in a 55G right now and have been in that tank for as long as I can remember. They are both the exact same size(4") I'm positive that the FH is a male but idk about the RD. I think its a male as well... I hope not though
 
Whats as long as you can remember. If its over a year both those fish should be pushing 8" at least. Also in my opinion both of them should be wet pets in anything under a 180. At least a 75 for each fish.
