Last night, I bought 6 guppies(4females and 2 males). I took all the steps, I know I did because all the other ones are acting happy. But one male started trippin, he started swimming fastly up and down one corner. Then he would swim into the plants and get stuck, then when he gets out, he goes to the same corner and does it again. All the other guppies are fine. My tank is where it should be, I've had my platy for over 2months and she good. Any idea's??? Is he tryin to impress the females??
