Wow! New to this, sorry. anyhoo picked up two RFA at the LFS and needless to say the gal working was supper busy and yanked the poor RFA’s out of the display tank they were in. Didn’t really pay attention, because I’m checking out the next purchase after these poor guys. The little one attached to the rock no problem, was there for a day and seemed to recover from his previous home. No big deal, but the bigger one had to be held in place for about 5 minutes before he seemed to attach to the rocks. Nope for both. The first night the big guy seemed to roll around the tank for an hour while I’m trying to catch him. Got him, had nothing to put him in, so grabbed the nearest thing, a ramekin, yep a ramekin. Don’t ask. The next day the clowns decided to play tag with the poor guy, so I pulled him out, ramekin and all, and put him in my QT. Lasted a day and he’s rolling around the tank there. Dude! I come across this post about a PVC cap, HUGH DIFFERENCE! Dang! It works!! Will definitely be using this trick in the future!!! Thank You! Thank You! Thank You!
