Hi all,
I have a zebra danio in my tank that looks like his spine is bent about 30 degrees, this has gradually got like this over the past 3 months - is it just old age he is about 4 yrs old? His brother looks fine. Oh and he now prefers the top of the tank in the jet stream of the power head.
55 gal tank and stats were good / normal last change <1week
Many thanks
David
