I guess I got lucky. Rescued ours from LFS. Was sold very small and in a 75 for almost 10yrs. Over six inches brought back to LFS and put into 120gal. We brought it home along with a Koran angel and put in our 180 FO tank. Is now 8” at least. Mine is a perfect citizen to all tank mates. We did put in a powder brown med size after one year and the Sohal almost killed it in 30min. We removed the PBT. About 2 months after we got the Sohal we added a scopa to the tank. We decided the tank for 3 days and then released. The Sohal never even paid any attention to it. We did the same when we added a majestic and emperor angel. The only fish that bothers the Sohal is Zeus the Koran which is the same size and is actually much more aggressive at feeding time. They usually just avoid each other. We also feed several once’s of large frozen food 2x/day and Sohal is very very fat! I think this helps with temperament. In our 180 we have jewel eel, Sohal, scopas, Koran angel, emperor angel, majestic angel, harlequin tusk, very large porcupine puffer, foxface, niger trigger, red tail trigger, and Picasso trigger. This is an agressive tank. I mostly worry about the majestic as it is the smallest in the tank. The niger is getting big and kind of agressive. Will not add anymore fish. We have a peaceful tank for what it is if you all can believe that! It is very open with lots of places for each fish to be and they all have their own sleeping spaces. Here are some pictures. I feel really lucky now, knock wood! I would try the Sohal since it’s small and see how it’s personality is seems like they are all different like people!
