Also I like to get mine as small as possible to watch them grow and interact with them to let them know I'm not going to hurt them. My ropes are very docile and will let me pick them up almost out of the water. They will eat from my hand and are very inquisitive when I'm doing stuff in the tank. The big female del is also quite tame. The hiders are more "feral" I guess you'd say, the moke is pretty mellow though. The new del in grow out eats from my hand and will bump me to feed him if I'm doing something in the tank. I wish I hadn't rewarded that behavior honestly. It's kind of a pain lol.
