Just got back from weekend from home ... the baby ray has grown considerably and is fat. Eats big prawns as opposed to puny shrimps - takes no crap from jar or aros.
When it was swiming while taking aro food on surface
i noticed that the belly is pink 
Is it normal? From my memory he did not have a pink belly before, but i don't remember. The temp was set at 27C now upped to 30C (like the other cycling aquarium).
The ray is still pigging out as usual and swims around (pix taken yesterday). The appearance on top is fine
Should i be worried?
PS: The tank is bare bottom. No idea what water parameters are (got only the nitrite liquid test and that reads around 0.2-0.3). From memory (could not find PH liquid tester), the PH is around 6-ish. The tank is not new and aros, endli bichir lived there for awhile already. The water is permanently salted. I use dechlorinator also.
