Will ghost glass catfish eat tetras?

Yes, ghost glass catfish (Kryptopterus bicirrhis) are known to eat small fish, including tetras. They are omnivorous and opportunistic feeders, and will prey on any small fish that they can fit into their mouths. Ghost glass catfish are nocturnal predators, and will often hunt at night when their prey is less active. They may also hide among plants or decorations during the day and ambush their prey.

Tetra owners should be aware that ghost glass catfish can pose a threat to their smaller fish and take precautions to ensure the safety of their tetras. This includes providing plenty of hiding places for the tetras, such as plants, rocks, and driftwood. Additionally, it is important to keep the ghost glass catfish well-fed with a variety of foods, such as pellets, flakes, and frozen or live foods, to reduce their likelihood of preying on other fish.
