I’d bet the tetras killed it and then the bichir finished it.Got them. They are very fat, but mouths are to small to swallow Cichlid gold pellets, and didn’t ask what they were fed on. The smallest tetra went Missing. Who is the culprit here...the peaceful Cory catfish, there own group, or the murderous water lizard ?
I feed my cories flakes, they are good for even the smallest fish. It will really scavenge off of sparky’s mess though.
