So today I go and check on my tank... I have two gudgeons one is a female that is super brightly colored and the other one is an unknown... Not as colorful but still a really pretty fish. I dont know if this one is male or female... Anyways today I was watching them and then the female started flailing its fins way out and chasing the other one... She looled beautiful while flailing her fins but I dont want her stressing my other gudgeon out... There is plenty of hiding spaces and 3 caves, so I am very confused as to what is going on...
