I`m from Norway and I`m new on this great forum!
I have 5 clowns in my tank and two of them of course developed ich. This is now cured, and none of the other inhabitants got the parasite

However, one of the clowns is really skinny and doesn`t seem to gain much weight. The interesting thing (to me) is that it behaves and eats just like the others, and also has the strongest colour of them all. Anyone who has an idea as to why?
(I`m sorry if this question has been posted before, but Im new to the forum and haven`t learned how to find my way around properly yet, and I`m a bit keen to find out about this as soon as possible in case I need to take some measures fast)
