So I have 35 neocaridina in a 125 planted tank with bladder snails. One of my red neocaridina has a yellow patch im not sure if it's just his internals showing through a childish shell or what. So any ideas would be helpful. Sorry for bad photos he's always on the move so it's hard to get a good pic. Also the water is cloudy because I just vacuumed the sand.
