update: i did a 50% water change and didnt put and chemicals in there. datnoid looks okay but im still worried about him. the two peacock bass looks like they are gasping for air. i got a breeding net and hooked it across the power head and put the peacock bass in it. the rest of the fish are fine. i think it might be the jungle lab water safe plus tablets i put in my tank. those tablets removes chlorine, chloramine and heavy metals, reduces stress in fish and stimulates fish's protective slime coat. this is the first time ive ever used these tabs. all the other meds had no effect on my fish. ohh and i did not have lotion on at the time when i was cleaning my tank. every time i clean my tank i always wash my hands first.
