View Full Version : pearl scales

08-22-2008, 08:26 PM

i have recently taken ownership of 3 pearl scales and they are only young so are yet to grow. They are in a 30 gallon tank and they seem to be ok apart from the fact they keep swimming to the surface taking/blowing bubbles then sinking again. After this they either release the bubbles to the surface or drift back to the top and do it again.

Any thoughts as to why this maybe??
