Possible sick fish? Help!!

Ok. I have a velvet swordtail and since the day I bought him I never saw him eat. He always hungout at the bottom of the tank while the others feasted away. He always floated motionless and moved slowly. I am not noticing his mouth doesn't move and has turned white and is spreading up his face. Anyone know what going on? What should I do? Thanks

 

How are things looking today? How long since you bought him? COuld he have been sick when you bought him? Most stores will do an exchange within a certain timeframe.

 

I bought him about 5 days ago. Each day the white dis-coloring around his mouth grows and my first instinct was that he was sick from day 1.

 

I'm afraid your fish is probably sick with fungus or columnaris or both. Get some Maracyn I and Maracyn II, and treat the tank according to the directions. You will be using these medications at the same time. You need to quarantine this fish if there are other fish in the tank, and put it in a 10 gal. tank if possible so the amount of medication you use is minimal. Follow the directions exactly, and don't get excited when the water turns very cloudy. This will happen, so don't be alarmed. Just make sure you have lots of aeration in the tank while using these meds. Add an airstone if you can.

 

Ive noticed that swordtails are very susceptible to fungus and fin rot. Hmm wonder why???
