i noticed in the other thread that we are fortunate enough to have some fish hobbyists around on here, so i'd like to ask a question
i have a tropical fish tank with 2 danio's and 5 really tiny other fish in there, however the water on top of the tank often gets like some white bubbles that wont pop and they form a layer over the top of the tank, what is this?? and how can i sort it??
i also have lots of goldfish flakes that i got given, would i be ok to feed these to the tropical fish?
