Thank you for all this. Every time you write, I learn so much new. And I feel more appropriate too, as a rookie. Good for my humbleness.
FD: They swallow rocks & stones to help crush and grind up consumed bones and hard food objects in their stomach for easier digestion, much like birds do.
TBTB: I didn't know this. Ours here are on bare bottoms. Do you have a reason to believe ours are endangered by not having rocks to swallow?
FD: I've had 200mm cylindrical air stones take 3 - 4 weeks to be vomited back out.
TBTB: Amazing. That long...
FD: Nothing wrong with them swallowing things but you can reduce sharp edged objects if your worried.
TBTB: Not quite that general. Several of our RTCs swallowed plastic plants in our prior life in the NY state, which passed into intestines and got stuck and killed them.
FD: Use a bigger sized smooth net and cover up the eyes with a wet cloth next time. You can see when the fish is anxious and when it's relaxed. Just wait until it's relaxed before lifting out of water.
TBTB: Are you saying fish can relax when caught and held against their will, only if the eyes are covered up? I cannot fathom this, but I am sure it is my inexperience.
FD: I catch with a silicon fish landing net and then scoop fish out of the landing net with a home made fish sock - black rip-stop nylon sheet. No bottom, for easy release. It doesn't absorb water and fish slide out.
TBTB: Do you have this black rip-stop nylon sheet fish sock photographed and discussed more in detail anywhere? I employ a similar technique but with a pillow case or a bed sheet. It sounds your way can be way easier.
FD: Also, try to keep calm and relaxed yourself when moving fish. RTCs pick up on your energy... In fact: get excited (without moving) prior to feeding your RTC tank and you will see what I mean.
TBTB: On the surface this seems bizarre

But I believe you'd not state this lightly. So it is likely me. ... BTW, how do you get excited on-demand like that and while remaining motionless? Not that you need motion to get excited or the excitement translates into motion necessarily...
