I'm cycling a tank with TSS and 4 guppies. I don't intend for them to be in the tank for the long haul but I don't want a fish to suffer either. I noticed one of them wasn't quite as strong as the others, always hiding and barely eating. Tonight I noticed clear poo! Not a good sign! Guppy transferred to tupperware without any trouble (I know they can kinda be dumb but this was clearly not right) and poo still attached. Opinions?
