i just bought a golden striped maroon clownfish and he was moving around all day yesterday when i got him and he even ate to as soon as i got him home, well today i came home and hes swimming in one spot and will not move from that one spot i checked the ammonia and it was a little high so i did about a 10% water change and the ammonia dropped back down to 0 but the clownfish still isnt moving around, could this be because of the shock from the ammonia and because hes new to the tank i just want to make sure i did everything in my power to make sure hes ok considering he was a pretty pricy fish.
