What I do, is I take a pair of cheap earbuds, put them on, and then put sound-reducing headphones on over them. Blocks out all other sound, so you don't have to listen to background little brother noise!
My adventures in keeping Indostomus crocodilus, the crocodile toothpick fish. AKA armored stickleback, paradox fish, and freshwater pipefish. Care is (to the best of my knowledge) exactly the same as Indostomus paradoxus.
