Need some input please

I'm concerned with one of my daughters Platy's
Over two weeks it's become rather skinny. I see the fish eatting so I don't believe it's starving.

The problem is the MM male is obsessed with her! He doesn't leave her side ever!
Anytime the other females swim by he chases them away. In fact I caught this MM darting at one of the females yesterday.
I've asked "Grandpa" for his 35 gallon tank/stand set up which just sits there empty.

In the mean time how do I help this fish?
Is she sick or just stressed out?
She clamps her fins down when ever this MM male is around. But when she swam close by me I noticed her side almost looked leathery? Not sure if that's the best word to use. Anyways the best photo I got were these ....


I added a piece of wood (been soaking for a long time to get tannins out) for a new hiding place.
But he has her cornered to one side of the tank

the only other tank I have is a 5.5 g for the fry. I also have a fish bowl but it's small ....



Here she is about 1 month ago

15gallon tank
temp 27-28

last readings on the 24th (took kit back as the kit was expired and 1wk old and ordered newer one)
PH 7.4
Ammonia 0.25 (<- I know. working on it!)
Nitrite 0
Nitrate 5

I've continued to do daily water changes ....


There Diet
Omega One Natural Protein Formula Flakes
blood worms
peas


In the tank are
mickey mouse male
reg swag platy female (the one that I'm having issues with)
sunburst platy female
dalmation lyretail molly female



What do I do ???!!!

He shows no intrest in the other females? Whats the F/M ratio.

IMO seperation is one good idea... But what happens if you re-introduce her to the tank, he may turn on her...after she is seperated he may find another target.

Another option ( your not at capacity ) buy more females and hope one recieves his advances. This sounds to melike a spawning regection

Are you increasing your hardness in there? All livebearer fish are harder water fish in general. Your pH is good for them but if you are only raising pH and not hardness that will affect all the fish in there.

Lower down the temperature as I find fish tend to be more active/aggressive when the water is warmer.

He does try but it depends on the day.
Yesterday he charged at the sunburst platy when she came around again.
1 male : 3 female

How do I do that?
The API 5 in 1 says;
GH 30

Just checked temp and it's sitting at 25

[jobber604]

They'll do fine. Once the temperature decreases to about 25degrees, the fish's mating impulses and aggression lessens. Increasing the hardness of the water will definitely provide a healthier environment for the fish.

this is a good thread regarding GH:
Adjusting hardness in your aquarium

"GH can be raised with either aquarium salt, equilibrium or replenish. Follow the dosage for your particular fish but an average level is 5 degrees. If it is a fish only aquarium salt is easy. If you have plants, use either Equilibrium or Replenish. One is a powder the latter a liquid, preference is yours."

That's really low. Have a look at our thread on the water in the lower mainland, Victoria's water is no better.
Add salt and alkaline buffer to fix.

Correcting hardness will likely help with the aggression as well.
