Have you tested your water?

Yes

If yes, what is your ammonia?

0 ppm

If yes, what is your nitrite?

0.25 ppm

If yes, what is your nitrate?

5 ppm

If I did not test my water...

1. ...I recognize that I will likely be asked to do a test, and that water tests are critical for solving freshwater health problems.

Do you do water changes?

Yes

What percentage of water do you change?

21-30%

How frequently do you change your water?

Every week

If I do not change my water...

1. ...I recognize that I will likely be recommended to do a water change, and water changes are critical for preventing future freshwater health problems.

Welcome aboard

Other than the positive Nitrite reading don't see anything visibly wrong with the fish.
Are the fish eating?

Welcome to the forum!
I’m not seeing anything wrong in the pictures, could you describe what the issue is?
One thing is that that level of nitrite can be dangerous, how long has the tank been set up?

 

[clive wright]

the tank has been set up for about 3 weeks almost 4. and yes the fish are eating.

earlier i thought i saw somthing on their mouth sorta like a fungus. if i see anything strange tomorrow i will let you know. it just kinda spooked me and i wanted to make sure everything is ok

Your aquarium is still cycling that's why you're getting a .50ppm Nitrite reading. Don't overfeed and keep up with the water changes eventually water parameters will stabilize.
Don't forget the dechlorinator.

Agree
It usually takes a tank about 8 weeks to properly cycle (meaning to build up enough of a population of ammonia and nitrite consuming bacteria) before you add any "non-sacrificial" fish.
I use the term non-sacrificial because it s a crapshoot as to whether or not any fish added before the cycle is complete, will make it.

what do you suggest I do, if i keep up weekly water changes will my fish be ok?

Weekly won't be enough as shown by the "fungus" on your fish. Do enough water changes to keep nitrites no higher than 0.25ppm, so your tank is due for 50% water change. Test for nitrites everyday. Dissolve about a pinch of salt for every 5 gallons of water and then add the dissolved salt into your tank to prevent further nitrite poisoning.
