My Green Arowana had tail rot and i'm treating it with Maracyn-Two. It is a five days treatment and she's on her third day of. Cloudiness of the water is expected but I would like to know if it is just normal for my Arowana to stay on the bottom of the tank during her treatment?
The cloudy water is due to the antibiotic killing nitrifying bacteria, so you now have an ammonia problem or a bacterial bloom. That is what is affecting the fish. Discontinue treatment and change 25% of the water. If you are using a carbon filetr, change the media. Tail rot is almost always caused by unsanitary tank conditions. In almost every case of tail rot we have ever seen, the aquarium was either too small, under-filtered, over-fed or was not getting regular partial water changes every three to four weeks. If all you are using is an outside power filter (one of our MAJOR pet peeves), add an undergravel filter. Make sure you feed correctly. If the tail rot does not go away with proper tank management, medicate with Aquatronics Spectrogram.
