basically the title i had euphyllia eating flatworms in my tank and i only owned one frogspawn so i just threw it away and i havnt seen them in about 3-4 months so im wondering if you can starve them out by removing the euphyllia or if they are just hiding in rocks? they didnt bother anything besides the frogspawn and about a week after i removed it i stopped seeing them so of course nothing is bothered by them now either but now i want to add some euphyllia back into the tank.
