Hey, my flowerhorn has been extremely boated and hasn't pooped in over a week. The other fish in there has white stringy poop so I thought he had parasites and maybe transfered it to my flowerhorn. I tried a salt soak and nothing happened. My flowerhorn is swimming and eating fine, just no poop. When I had put in the medicine general cure api, he turned a dark color and sank to the tank and is gasping every 30 seconds. Is this a normal reaction? The smaller one just sank to the bottom too and is barely moving. I just put the medicine in about an hour ago. Should I take them out? I'm extremely worried as he is my favorite fish.
