i just purchased this today... actually, he is still at the LFS and holding it for me till my tank is ready to go. Labeled as Black Wolf (H. Curupira) and i had to get it because i wanted one really bad and fell in love with the wolf as soon as i saw him. luckily they were nice to hold him till i'm ready (maybe a week or two) cause i will be getting a getting a tank and will have it up by this weekend. i was just being cautious in case anyone got him first since i never see them here in SF. Sorry for the low quality pics from the my camera phone.
Here's my new 13" Hoplias Curupira in a 4x2x2 tank which ive been patiently waiting for. I had him for several days now and has been pretty calm at first. now he/she is really starting to open up especially during feeding time. So far i only fed feeders at first and now im giving nightcrawlers where they dont last 1 second once it hits the water.
