heres a lil video of my jardini eating giant canadian earthwarms. the bichir in the video is 18" long. both in a 90 gallon tank..
yepz. i have a bin full of them that i use for bass fishing in the summer. they multiply like crazy and requires little to no maintaince. since i dont fish in the winter, i use them for food.. they are as thick as your pinky. i would hand feed but them to my arrowana, but them worms are strong and feels wierd wiggling between my fingers.
