Ghost Knife

The tiger barbs should also be fine, ive got a dozen living with a 8inch ghost. At the moment he couldnt fit one in his mouth, but i really dont see it happening in the future anyway.

The smaller tetras will most likely be a meal however, my ghost wiped out a school neons in one night, and this was when he was only around 4inches.

The tiger barbs may be okay during the day, but the knifefish will get them at night.
