Oops! I forgot to add a

 

[Red Devil]

I started feeding him frozen bloodworms. He seem to be eating well. Curious little bugger too which came up to the surface when I swirled some BW in the water.

(LFS fed him live tubifex *yucks!*)

That is great that he is so outgoing and eagar to eat..very good.. definitly must be in carapo family.. mine is so timid..

Just fed him dinner of frozen BW and witnessed him feeding! He nuzzles his mouth against the sand for food and sucks up the BW like the way we eat long strands of spaghetti! Appetite is healthy

Couldn't take a video footage as he's shy when I turned on the bedroom lights. Resumed eating when I switched the lights off.

Mine is not the same as yours.. i have had mine for 6 weeks.. it took me 5.5 weeks to ID him.. here is his picture.. he is in the Hypopomus family.. close to yours but yours is aggresive type mine is shy.. and small mouth. i am going to try and make time later to look at different pics i have to see if i see someone who looks like yours..




his diet is blood worms also.. but never see him eat..they are gone in am..so he eats at night when lights are off.. he is almost 10.5 inches.. with that tail

For this species the longer the tail the better to attract the ladies.. so i also know he is male.. [of course never will i find female} thank you... and congradulations on your beautiful knife too..

How long is it? It looks pretty young still, so it's hard to tell just by the pattern. If you could get a close profile shot of the head, it would make it easier. Otherwise take your pic:

BTW, Aranos, thank you so much too for posting this list of spp. A great way to start doing my research too (as inspired by Red_Devil's hard work for spending 5.5wks identifying her knife )

Thank you! Also, at least you know its gender from the length of its tail. I think almost 99% of us knife owners don't know whether ours are male or females LOL
