Hello reefers, I have 2 baby clowfish I just purchased yesterday on my local reef club on arrival I noticed one was breathing rapidly, once I got home I acclimated then to my qt tank 5 gallon with hob filter heater, and dosed rid ich plus. the next day and the clown that wasn't breathing fast still isn't but has Stringy poop that just hanging off him. While the other clown is still breathing rapidly.Tank has been running for over a year. Any medicine I should go buy or is rid ich plus a good choice.
