swimbladder problem for guppies?
Does anyone know much details about swimbladder disease and it looks like I have one guppy with the same, what could I do to treat it? (The fish looks like loses its control most of the time and wandering with the current) for 3 or 5 days since today.
Also, in my aquarium I have not kept gravel at all. Is gravel really necessary for aquariums or is it ok not to have gravels in aquariums with guppies?
