Ok, I know what one of these pics are, but the other I have no clue and I'm hoping it's a sponge and not a flatworm. The other pic are apastia anemone's that have attached and multiplied on the glass of the fuge, will they spread and go into the main tank if let alone? They'd have to travel up the pump, would they make it? Look forward to the replies, thanks!
