Ya I was worried at first but it wasn't that bad just watched him to see where he was gonna go fori'm surprised it didn't go for the fingers.
Nice setup. Super clear water. So your training him him not to fear your hand? Interesting!
im mostly trying to get him not to be super shy/skittish for the first time yesterday he would come up to the glass to me I usually put his food on a steel leader and hang it in the tank mid water so when he's done eating I just pull the steel leader out with the left over food but it is fun hand feeding him though
