I have a 20 gallon tank, with mainly Platys in it, as well as one male Mollie, the babies are a mixed Mollie/platy breed. I am switching to a larger 30 gallon tank, and trying to catch the baby fish, which are about 3 weeks old, is darn near impossible. I dont want to freak them out too much by chasing them with the net. Is there a good way to do this or is it just a game of cat and mouse? Ive been breeding these fish for about 2 years, and this is the first time that ive ever had such an issue trying to catch them. Its like they all of the sudden got super fast! And the tank is emptied as far as decor goes as I moved it into the larger tank. Any help is appreciated!
