			 I've always wondered why my RBTA doesn't bubble?  I've seen photos of beautiful BTAs that are bulbous and bubble up.  On the rare occassion I will see some of the tentacles from my RBTA bubble but it isn't that noticeable and most of the times the tentacles are straight. 
		
	
		
		
		
		
		
	
		
		
	
	
	Anyone have any explanations?  |
