I keep 4 Golden Rams in a community tank and they seems very well, happy and healthy now for about 8 months since I bought them. One of my Rams display odd behaviour though. I'm not sure whether it's a male or female but it keeps sticking it's bum up the bubbles ! ) Let me explain: Apart from the normal filter I also have a long blue aeration stick that makes loads of bubbles. And this one particular fish just seems to "sit" there quite often with it's backside up the bubbles ! Any vague idea why ? The fish seems very healthy and happy otherwise and in-between resting on the bubbles it swims and eats quite happily. I'm just curious if anyone has any idea why or have witnessed similar behaviour by their fish.
