I can't thank you all enough for the quick responses! It breaks my heart to see him like that, I just want him to feel better.
Since the five gallon is a new tank, the fish man at the pet store told me not to put the carbon cartridge in the filter. He also told me not to wash the rocks when doing water changes for now? He said the 'good' bacteria on the rocks will help keep the
ammonia level down... are these true? Please forgive my fish ignorance, I'm working on it!!
Lastly, He does eat a little, only about 1 pellet in the morning and 1 at night but isn't much interested after that... I can put the ampicillian on it... before I do though, does anyone know if it is bad to give it to him while I'm doing the Maracyn Two treatment?
Thank you all so much again! I really appreciate your time!
