Bought a 10$ frag with 4 z's on it only one was opened and had really nice color so I took a chance with them but they have not opened they r on my sand bed anything I can try to get them to open???
no dipping needed, just give it time or maybe it is light sensitive so try moving it to a different location. Good luck with it, are these the ones I wanted as well?
As long as you are sure you have good parameters you want to make sure you have them in decent flow.
If not , you can try holding them near to a power-head for a minute or so and then place them in a location with good (not crazy flow) and they with usually open after that.
You do not want to be moving them around a lot, they do tend to pout.
