After you acclimate it properly(imo
at least an hour of drip acclimation) Scoop it into a net and set it on the substrate where you think you might like it to go. Make sure there is a lr
with maybe an overhang. It's going to go wherever it wants to anyways but if you give it an overhang it is more likely to attach to it. Turn off the powerheads and give it a couple of hours to attach itself. If you leave them on they will just push him around and he may have a hard time attaching or get caught in one. Don't panic if he looks like crap or shrinks up to nothing but a blob. You might even want to turn the lights off for an hour or so to help him get used to your tank first.
