Are My Fish Mating???///Whats the Problem with my Fish???
To give a background...I am an ametuer at keeping aquariums. I had initially 4 goldfish, 2 Kapra (Indian Variety), 2 Catfish, 2 white tetra and 2 White Fish (Which i assume as White KOi) in a 45 Litre Tank. I changed my fish an year later, returning the Grown ones and retained only the Tetra and Koi and brought 2 Lion Head Gold Fish and 2 Black Angelfish few days ago...
Now the Problem... OUt of the 8 fish i have now... The KOI's ( Correct me if they arent KOI's PICS attached also tell me what variety they are) are very excited and are always roaming the tank very fast and never resting. We assumed because of Excess space and new fish now....
Today i have noticed a brownish extension which comes and go on and Off in one of the KOI's backside ( Attached Pics... Not Very Clear Though)... Kindly tell me if they are gonna mate or is there any problem...
Also advice what should i do if they are mating
The White KOI (white Fish) are barely 3-3.5 inches long.
Please help ASAP with advice
