ok so i got a new tank for my ever growning fish (especally iridescent sharks) it 25 gallons. this is now a good size because my sharks are between 2-3 inches long (2 of them). so they were in there for about a week and they seemed fine, then one day they seemed less energenic and they are now just laying on the bottom, not moving unless nessary. the tank stats are normal and i'm getting comfused.... none of my other tanks have ever done this. i am hoping this may be characteristic of the iridescent shark because i have only had them a short time now. At least then i can be at rest with their health. if not , what is causing this ?? i have done a water change today(about 10% as to not disturb them if they are really stressed) and i am completley lost as to what is wrong! thanks for any help.
