Ram

Question
We have a tank with various fish one being a female Ram recently we added a male Ram who got on fine for  a week or two but he now has white spots or bubbles (not sure) covering him and doesn't look as happy any ideas ? Many Thanks

Answer
Although I am not familar with this particular fish what you are describing sounds like ick.
The bad news: It can be fatal
The good news: It is easily treated with an ick medicine.
(read the instructions)
Does it look as if your fish has been sprinkled with salt?  That is the best description of ick.
Also you can look up ick online to see pictures to compare with the spots on your fish.  
Good luck!
