My angle fish are acting oddly worried they are sick. When I switched tanks I added half the water don the old tank I'd really like some suggestion on whatshername be going on please
 
I saw your other thread. So you upgraded tanks but you changed the filter? If that's right then you basically uncycled the tank so the tank has to re-cycle. Toxins are going to increase and can stress fish without proper water changes. You need to start testing the water with a good liquid test kit. I'd start with a 50% water change with dechlorinator and read this: I just learned about cycling but I already have fish. What now?! - Aquarium Advice
