Sure do about 12 I just love themBubbly! Do I see some harlequins in there?
I put the bubbles in back and took the power head and put it in the bigger tank just got it yesterday and didn't arrange my tanks yet .but it's done now looks nice.Lots of bubbles, I would suggest putting the bubble line at the rear of the tank so you can watch the fish more clearly. Interesting stone/plastic stone set up. I like it.
