Those guys in the first pic are all fully morphed. I actually morph them in a container with an inch of water and full of plants. They were initially kept fully aquatic and when they first started to morph I dropped the water level to three inches but found a few were trying to drown themselves by lying on the bottom of the tank upside down. Now at the first sign of gill loss I put them in that tub, give them daily 100% water changes and feed live white worm as I didn't want bloodworm fouling the water. They morph within a couple of days and I hold them for a further three days to make sure they are ok, then place them in the bigger tank you can see in my first post. I have had three recent morphs drown in that tank but it was due to them getting inside a hollow ornament, I removed the ornament , lesson learned on that front.
