I bought a Columbian Shark about 5 weeks ago for my 55 Gallon fresh water. He seems healthy but has been swimming in circles for the past couple of weeks in the corner of the tank. he has grown substantially. All my other fish are healthy and do not demonstrate this behavior. they consist of; rainbow shark, bala shark, swordtail, neon tetras, pair of blue rams, gourami, and an algae eater. I have heard that they like a slight salinity. any suggestions? (will provide another home if unsuitable). Thank you
