Please Help. (Kind Of Urgent)

Hi,

I'm new to fish tanks and have had this one since august. Just to summarise:
15 l Tank
Internal Air filter
5 White cloud minnow
No cover
Temp 17 - 19 in fluctuations
25% water change everyother day
use tapsafe

Water parameters (Tested with dipstick i know not very accurate):
Cl2 = 0.8
Ph = 7.6
Kh = 3
Gh = 16
No2 = 0
No3 = 10

The problem is one of the fish has split fins and is very thin. It will not eat and I have separated the fish from the main tank to try and feed it separetly with no success. I think one of the fish is bullying in the main tank and I dont know whether it is male or female.

My priority now though is to get the ill fish back into the main tank. But it will not eat and will proably just be bullied again.

I have attached a pic of the fish.

I think there may be an unbalance in the genders.

Any suggestions are appreciated

Sam

Give them plenty of plants to hide in as your other tank looks rather bare then at least the bullied one can have a chance to get away
