So I'm a beginner at this. I bought two Columbian sharks, two red tailed black shark and a pleco. The first night I had the tank light on (because the guy at the pet store said to) and I woke up the next moring to find my cs and pleco dead. I went back and got a refund and bought one more columbian shark. I've noticed that every time I turn on the tank light the cs likes to follow his reflection. When I turn the light off it swims around the tank calmly. I'm scared to turn the light back on cause I don't want it to get exhausted and die like the first two. I got the water test and it's good. I don't understand why they died. I have been feeding them flakes and for the pleco I dropped a couple of wafers. I've also slightly added some sea salt. I don't want my cs to die. Any suggestions?
