So yesterday I woke up and found one of my angelfish stuck to the filter I took him off and he was having trouble swimming so I put him in a breeders box and he just couldn't stay upright, but he looked fine otherwise until he died that night. Now this morning I woke up and one of my phantom tetras is doing the same thing. Swimming but cannot swin upright and straight. The water is fine they are just swimming weird. What is going on.
Thanks
