Thanks for all the comments. I took the pics from pretty far away (so the flash didn't spook any of 'em) and was kinda surprised how they came out. I had to resize the pics to post 'em here, but when you look at the pics on my computer its even brighter.
I could talk about balas all day,,, but I'll try not to

Shamu, in the wild they've been known to get 14-18" plus in size. In captivity they can still regularly reach 10-12" or more. When they get that size, I'll need a bigger aquarium.
im-trying, you noticed that too, huh?

yea, he's nuts. actualy in the first pic up there (the first one I took) he was working on his nest behind the pipes (poor guy needs a girlfriend) and saw the flash, and immediately swam to front and puffed out his gills - kinda looks like a betta when he does it. if you put your face up to the aquarium, he'll do the same thing, charge then swim away, charge then swim away. If you look in the third pic, you can see the pile of stones where's he picked up and moved enough stones to get a hole about 4" wide and about 1.5" deep at middle.
I'd have to think, but I'm pretty sure those two are somewhere between 2 & 3 years old. Properly cared for, they can live up to 10 years, though VERY few ever make it that long. The pet store I used to go to, the owner had an 8-year-old bala over 11" long and really fat.
