I'm very interested in these types of catfish (The Paroon Shark and Iridescent Shark) but everywhere I read, says they get absoulety huge, but I tend to take everything I read with a grain of salt. I was wondering if anyone on this forum had, or does have these kind of catfish. Any info would be appreciated. Iridescent Sharks I seem to find at every LFS around here, and I've come across Paroon Sharks as well. And while I havn't asked about the Paroon Sharks, the people at Petco said the Iridescent gets 10-12". But, if anyone could give me any info, that'd be awesome.
