i have 1 tank -3 yrs- 33 gal- and am going to add another. Waslooking at a 29 gal bio cube at lfs. Are they good systems or is the filtration system weak?

recently added a pair of rosy barbs to 3 yr old community tank. they get in the "current" and go round and round and round and round they drive me nuts . is this normal behavior or should they go round around the big white bowl?

do all BN eat algae or are some better than others
