Have you not got them anymore? Pretty good looking but I just did a google search and yer they seem agro!The fish that zips by is a Albino Hemibagrus nemurus/ Asian Redtail Catfish. Regular Asian Redtails are known for being pretty aggressive but I've heard Albino Asian Redtails tend to be more tolerant. I wouldn't count on that though as I haven't heard it said enough or any proof for me to think the statement is in any way reliable. I've kept them myself only once and had no issues but mine where juveniles which can make all the difference in the world.
