a 20 to 30 mins dip for me i think is too long cos those of my zoos dint make it i guess it due to the long bath as that time i leave them in the FW and have a bath and dinner
later return to my room den i realise that these rocks are in the FW
and these 3 rook every polys seem to be bloated few days later they started to melt now left with few polys n my rock
