Yeah, mine still scare the crap out of me during feeding time. I drop flakes by it's face and WOOSSHH. It's gone in a blink of an eye.
BTW, what kind of plants are those?
FYI, your AFB will probably also eat fish flakes and small fish. I didn't realize mine were interested in fish, but I got suspicious when a fe cardinal tetras started dissapearing on me. Also a few young guppies I put in the tank also vanished. Afer witnessing it grab a young guppy, I moved it out of the cardinal tetra/pl*co 37 gallon tank back to the 55 gallon tank with the angelfish and clown loaches.
