to acclimate them ,set up a drip tube ,it takes about six hours taking some water out of the bucket ,every so often ,one word of caution, they breed like rabbits, i got about twenty to cycle my take ,and even with die off ,and the few my wrasse and trigger gnawed on i still have twenty of the darn things ,there are never any more babies in the tank ,because the huma and lunare eat them as soon as they find out they are there!! i have the black mollies and if you want some ,you can have them!you just have to come and get them.
