My female Sajica cichlid won't eat (Pics ;))

[js302]

Hey guys and girls,

My female Sajica cichlid won't eat.

I've got a pair in a 200litre tank. He is 3.5 inches, she is 2 inches tip to tip.
There are also 4 Cory Sterbai.
I’ve had them since November. The cichlids have spawned three times but always eat the eggs once they turn white.

Water parameters are great.
Feed is - Prima pellets, Cichlid Gold, BW, BS and frozen Mysis.

He eats like a pig and grows well.

She shows enthusiasm towards food, gets hungry and begs. She then tastes and rejects food, or doesn't take any into her mouth at all.

He has grown so much more than she has and I'm getting worried.

How do I get her to eat and grow.

4 weeks ago I treated for four days with weeks with Kusiri Flubendazole.
Her poop was white before the treatment, it’s darker now, but she still doesn’t eat.


Thanks in advance for the help...

Might be intestinal parasite. She swim around much or is she stationary? Does she show any signs of bloat?

She swims and looks very healthy.

Signs of bloat? Like an enlarged abdomen? No luckily she doesn't.

Wouldn't the Flubendazole have treated any parasitic infection?
I treated with it because she has not been eating. It's not that she hasn't been eating since the treatment.

Is she pooping? what does it look like? normal? any odd swimming behavior?

I've only seen her poop once in 2 weeks - you could be right.
It was white and stringy, I treated it now its dark purple/red?! Like his is.

She swims through the caves and, she swims everywhere and well.
