Powder Blue aggression, or playing with Powder Brown?

[ScubaSkeets]

I have a Powder Blue Tang and a Powder Brown Tang. Bought at the same time from the same quarantined tank.
The Brown is about 4.5 inches. The Blue is about 3/4 the size of the Brown. I'd say that 99% of the time, they get along great with each other, and with the other fish in the tank.
However, every once in a while, the Blue will just flip out, and dart around the tank, circle the Brown once, and as suddenly as he starts it, he suddenly stops and goes about his own business. There's seemingly no aggression (other than what I described, if that is indeed aggression). No nipping and it only happens for a split second or so. The two even buddy up with each other.
I will add that I have seen the Brown doing the "submission shake" to the Blue once or twice.
Has anyone seen this with their fish? Do you think the Blue is just playing, or do you think it is something that will get progressively worse into a real aggression?

fish can’t talk, so What you witnessed was “Tang talk”, …
….what you need is a interpreter

seriously tho, usually for aggression: 3 of a kind is better than 2… is the tank big enough?

is the tank big enough?

For the size they are now, yes. For full size, no. But I am in the planning stages on getting a 250-300G.

Tangs will fight every now and then and express dominance over food or area here and there. That's what tangs do to each other

Thanks, but there's no fighting. Just the Blue darting about for a split second. I've never seen them attack each other, and the Brown just seems to ignore the Blue when he does that.

That is aggression and will lead to one cutting the other rather you see it or not. Just a heads up. You can see those tangs dart like that when you are cleaning the tank and then you will find a razor cut on your hand. You didn't see it but you feel it later when you wash your hands. That are not darting because you scared them, its warning the other fish about something.

Oh they will fight sooner or later. Its what they do. My tangs will get into a little scirmish every now and then about somthing. Food, sleeping area, hey its 4oclock and I dont like the way you looked at me. LOL.

Good luck

What size tank are they in now? A 4.5 inch powder blue is big enough to rule a large tank and mixing them with powder browns can be problematic as with mixing any like types of tangs. 3 is always better than 2
