What To Choose

[j.c]

hey my mate has a 4ft fish tank 200L and had a problem with whitespot lately and he wants to know what type of fish would go good in their such as kuhli loaches and things like that. any help would be great.

1) Is he positive that the ich has been eradicated in his tank? He doesn't want to add new fish to an infected tank.

2) Has he got any fish in the tank at the moment? If so, what and how many?
