I have a hang over filter that creates a ort of waterfall effect, and it always produces a couple airbubbles in the aquarium, but when i puyt in frozen blood worms it causes a mass collection of these bubbles all ove rthe surface of the water, then be the evening when the blood worms are either eaten or sucked up by the filter the bubbles start disapearing, just wondering if this happens to anyone else... im sure its not soap, because they dont taste, or smell like soap, and also the turtle keeps its eyes open under water and he doesnt blink them alot or anything to show that it might be hurting his eyes. Any ideas? Thanks
