i just picked up a really neat catfish, i think it is a young H. wyckii however the wiskers are white rather than solid black like many of the pictures i've seen. also how long will it take the wiskers to grow back, or do they never grow back? he's missing most of one on the right hand side. i picked him up for 4.99 in a tank full of Synodontis angelicus(there were about a dozen on the bottom and they weren't labelled so the employee said they were synos)
