Hi i have a 12gallon planted tank thats been running for about 2months. I had 2 male guppies and 1female. The female had babies and all was well for about 3weeks. Then i noticed to male guppies color was fading and they wernt coming up for food. The next day one died and got eaten by my snails which i'm desperatly trying to get rid of. The the day after my other male died but floated to the top. About 2 days after i notcied a small looking worm type thing coming out of one of my larger babie guppies. It kind of looked like their poop. THe guppy was acting fine then the next day there was a hold right in the side of the guppie, and its still there. She doesnt seemed bothered by it only the occational rub against the rock as if she was iching it. She is still alive and eating and nothin looks wrong with my other baby guppies. And idea what this could be??
