Swordtail Stressed? Sick? Or Pregant Help!

[astaccz]

Hi I am new here on this forum. I have a concern for one of my fish. A swordtail that looks like a female. She hides behinds this rock and she looks squished but she is alive. She stays there for some time then comes back out. I dont know if she is being bullied or not. I think my tank is overstocked. I have two filter running on the tank, Emperor 280 and Top Fin 30. A heater which is set to 75-76 degrees farenheight. As for activity in the tank, I see my Guorami chase my male swordtails once in a while, and my shark (1inch in length) chase the tiger barbs. This is the fish I have in the tank.

33 gallon long tank
1 red tail shark
1 golden guorami
8 tiger barbs
3 swordtails (2 male and 1 female)
Weather Loach
5 zebra danios

I am going to give the 8 tiger barbs to my sister today when she comes because I see the barbs are fin nippers and always try to bite the other fish. What can this be? Any ideas? Thank you guys for the help. Here are links to pictures.

how long as your tank been setup?
How often do u do a water change, and how much, when was your water change done?
whats your water status?

My tank has been set up for about 2 months. I let the tank sit for a month when i added bacteria. So the fish has been in there for a month. I did not introduce them all at the same time though. Last time I did a water change was 5 days ago i think. 50 percent change. after adding water i added stress coat. I do 50 percent changes every 2 weeks. what do you mean by status? im sorry im new to fish keeping. btw thanks for your reply.

Ah. I need a kit to test for that. i dont have one. i have to run pick up one tomorrow morning as its 9 pm now. what should i do until then? quick water change maybe? do you think my tank is overstocked? i am giving my sister the 8 barbs.

 

[wrighty8529]

when u give them to your sister u will come about right on stock put her in something in same tank where other fish cant get to her if she is ok by tomoro do a 25% water change.

ok will do. im def grabbing that kit tomorrow. ill update you on the status of the reading. 1 more question. is the heat good at 76 or thats too hot. should i lower the temp?

 

[wrighty8529]

76f?

 

[astaccz]

yes thermometer reads 76 farenheight. they say the weather loach does best with cooler temps but i dont know how low i can go because of guorami

 

[wrighty8529]

75-76 degrees farenheight will be ok just don't let it go over 30c i run mine at 26c.

Also, I would add that the swordtail is very likely stressed being the only female with two males. It should be more like 3 females to every male. Otherwise the boys will bully her to mate, even if she is already pregnant.
