No Belly?!

[Rorie]

I have just been looking in my 90L, where all is well, other than one of my cardinals.

Under their coloured stripes is normally a plain, white/grey bit which is their stomach, which is curved to make, em, a fish shape haha. Well today i have noticed one of them is missing that! So the bottom part of them is flat! You cannot see this white/grey area at all!

Anybody know what this is? They have been on the same diet for the last year, no change or lack of food!

A sunken belly can be caused by various things - e.g. bacterial disease, fungal, parasitic etc.

Are there any other noticable symptoms?

nope, and all the other fish are fine. The cardinal looks an awful lot more pencil shaped now! Should i treat the tank?
