i only ask as my big female eats but not enough to keep her alive
she has never been bred with as no male is big enough to take her on
for the last few months 3-4 she has ate a little and i mean a little maybe 1-2 shrimps per dayand still no hip bones or dent
i know smaller rays lose weight faster but the ones we see with hip bones and dent cant have been feeding well for 6 months +

Am I right in thinking the ray in question is the least active of all your other rays?
Also I know you have substrate in your tank as I do, are there any small Snails living in your tank, I have thousands of these critters which I am convinced the rays feed on whilst pounding the substrate, these could be supplementing her diet if there are....just a thought!
funny you should mention snails as when i cleaned my jap mat out the other day there was loads
nothing has changed in the tank and no male harsses her as she wont stand for it
she has always been the less active
she doesnt jump on prawns or pellets like she used to
but after everyone else has fed she seams to go around eating the soft pellets
i think all rays slow down a bit with feeding once they are fully grown at 5 years
i was feeding a full mug of pellets and a plate of prawns per day but now still the plate of prawns but 1/4 mug of pellets
i just put it down to selling the 3 massive gold tinfoils but i now have the shoal of tinfoils back up to 7 and still 1/4 mug of pellets the tig is loving the extra left over food
she is still eating but not much
i know this is another strange one but has anyone else noticed that males seam to let preg females eat first before they feed
My 16 year old Marble female feeds as well as ever, all my other large older rays are the same, they all feed like pigs in all my tanks, all are on pellet too.
Your big female obviously has a poor appetite. This can happen to any animal, the fact she is inactive will stand her in good stead,she won't burn the weight off nearly as quick as she would gliding round the tank continuously as many do. She is obviously taking in enough nutrition to keep her weight reasonable.
I don't know where the hell these little Molluscs are coming from as I don't use live plants, probably some second hand gravel brought them in but they must be on the menu for the rays, I also first found them in my pre-filter, felt like grit, they are so small.
Regarding your last query I would say the insatiable appetite of a gravid females means they are always going to be on the food first, few people these days have manners, I'm sure they don't occur amongst Stingrays.
