I have a funny story about netting out all the trimmings of the Riccia.
The Maculatus are so comfortable in the Mini M, that they've gotten to full color point, and when I'm around they spend a lot of time following me around (hoping for food).
When I hide from them, they spend most of their time milling about (still zero casaulties or jumpers) in the open areas of the tank and in the tennellus area. They actually sleep in the thicket of tennellus (which I think has more to do with flow than plant).
So, upon using a net to get riccia trimmings out, I had a great deal of trouble getting the Riccia out, because the Maculatus would swim into the net and chill out in the net, and make no attempt to jump out or anything.
Which meant I would have to try to carefully guide them out or dump the trimmings out in the tank for them again. Even a few Amano's did this.
If I just lay a net there, these guys will gun for it.
