I had ordered an Ornate bichir, they told me it would come in at 6 in. and i had a 4 in. senegal bichir named finarfin (lord of the rings haha). the thing came in at 8 inches and i was quite hesitant to put them together but i ended up doing it, and it was perfectly fine for a couple weeks, then all of the sudden no finarfin. i looked all around the tank to make sure he didnt jump out somehow, through the heater or filter hole but nope. Totally eaten, and i didnt think hed fit in the ornates mouth but after some investigation i found bichirs have powerful jaws that can crush fish down to size so be careful with em
