Fish Fanatic
i have 2 gsp's in a 15 gallon tank ukg. been slowly making the water salted, heard they liked it better. one of my guys is lively and bold, and his colours are amazing. however the littler one is a bit darker, and although every now and then they have grey bellies (toward their tales only) my little guy will go from white to grey tale really quickly. Thought it might be water so did a change, water is not cloudy and does not smell bad. they both have those bright spots on thier heads, i was told this was a key to mood?? so what i'm asking is it normal for bellies to go grey for a while, and the green back darken? as some sites say "yes, this is normal" and others say, "no, not ever should they change" which is it please?? so confused.
