Ive had 3 male guppies in my tank for about 6 months, which have managed to survive with much bigger fish, I am not too sure how. But I recently went on vacation and my gf wanted to suprise me and got female guppies. I come back to see a bunch of little swimming things in my tank. It was a massive feeding frenzy and now im afraid all my fish overate. I cant wait to see what happens
