need help with female BD - heavy breathing

[Squid]

Need help, yesterday, i noticed my Female BD suddenly seem to be breathing heavier than usual, also when i dropped food it just ignored the food and not really active?
usually it will immediately go for the food i drop. not sure what is the problem with her.

I tested water for Ph and Ammonia
PH - 7.5
Ammonia - 0
tank size is 350 Gallon, with 180 gallon sump.
tankmate is a 24 inch super red arowana and a big King kong parrot which dont seem to bother my rays.

I did a 30% water change and dosed with Prime, not sure what else to do.
She is about 12 inches now and with another male BD.

before this i think i saw her covering the male BD or is it the other way around, not really sure.

what else can i do?
earlier today she seems more active, but still seem to be breathing heavier? and doing chinups, where her front chin seem to be blowing?


is it possible she might have been stung by the other ray?
or maybe she ate something which should not be eaten?

no new thing introduced to their tank.

maybe can look for any signs of aggression from other ray?

if water is all good, do u feed them any live food? maybe try deworm?

thanks bro so far have not seen much aggression from the male BD.
though when it comes to feeding time , they will both go for food before.

last night she took some massivore. maybe dose with prazi as preventive?
i dont feed them live food, only mp.

but i have a King kong parrot in the tank and i drop him some snails from my other tanks. could this introduce parasite?

it was before water change and feeding.
its weird, i did not do anything before that, just saw her trying tocover the male, or might be the male trying to cover her.

then when i dropped some food the male rushed for the food, female was not as active. i initially thought she might have been stung? i did wc and added some Mirage Vita

so far she is back to normal and feeding. hopefully she is ok.
