Typhlonectes natans- rubber eel/ caecilian worm.
It's an amphibian not a real eel, max size 2 feet, they are blind, great escape artists and look kinda like aquatic snakes. The are pretty hard to find though
. You may not like the look of them
, alot of my guests find them creepy. I have an adult pair, they have been with small fish for over a year now. I trust them 100% not to eat the fish. I have some expensive fish in with them, but I've raised them since they were a foot long. That said they definitely have the potential to eat fish, especially those stupid expensive ones that sit on their heads
. I'm planning on putting some pygmy corys in with them. IMO its cuz they have never eaten fish before, they don't know........ or they are just lazy..... its probably cuz they are lazy......
