Yesterday I bought a new bubbler for my 75 gall tank. It is the hose bubbler and runs the length of my tank. It created lots of bubbles! My Jack Dempsey is not coming out of hiding. Could the new bubbler be scaring or hurting my fish?? I had a very small bubbler in the tank before. Any input would be great. I love my Jack Dempsey and I am comcerned. He is not eating either???
