As some of you know I have had these two together for around 6 months now in my 130x24x26 tank - my Sohal is about 9.5" now and the clown tang is between 8.5 and 9". I've had the Sohal for more than 2 years and bought the clown tang from DD in January. This post is just a recap of the last 6 months happenings between the two. I guess most importantly I want to report that there is no aggression at all between the two fish which continues to surprise me. Having observed them for 6 months I am able to report that the clown tang is more aggressive than the Sohal. Also, the clown tang is far more active swimmer than the Sohal. The clown tang is not so aggressive that it tries to kill tankmates but it did harrass my 7" sailfin to the point I had to move the sailfin to the 150g tank before things got bad. As far as overall looks I prefer the Sohal tang by a large margin. The clown tang just isn't as striking as the sohal, the only time the clown tang really wows you is when they flare their tail and fins which isn't too often, otherwise they are pretty plain. They turn really bright orange when they are ****ed off. All the other times they are sort of a drab orange color. The sohal pretty much stays the same color all the time. So that is about all I wanted to write about, just my observations to this point. Obviously all fish have their own temperaments.
