I believe is the arowana that is making the sound. I used to own a big rtg that makes a drilling sound swimming playing against the water current.Some asian arowana can makes some noise .
Cliff.W.;4082165; said:Haha so it is my aro? Possibly? I'm gonna pay more close attention and see if it is my rtg. I thought I was crazy when I posted. Stu pie rtg eating pebbles so I cleared my tank gonna head to the fish store and find alt solution for the bottoms of the tank.
What do u guys keep in the bottom o the tank to prevent aronfrom seeing itself all the time and develope drop eyey?? I know some people float ping pong balls ontop of water. But the aro still sees himself underneath. Plz help
