I haven't posted on this thread for a while... all 3 of the giant Oto's are still alive and thriving ( actually Hypoptopoma sp. ) these are supposed to be Hypoptopoma thoracatum, but I suspect the one I named Sid is a different sp. he has much more personality than the other two... the other two are as good as any other pleco at glass and hard scape cleaning, but Sid is exceptional, and seems genuinely curious what's going on, outside his box... he doesn't beg like the Cichlids do, but seems intelligent when he watches us... even though he is a sucker fish, he has become one of Mrs. favorites, because he interacts with her...
I have ordered a 4th, just to see what I get, and get a better representation of the Hypoptopoma group...
I don't have any new an exciting pictures, that haven't been already posted, just wanted to update that they turned out to be a great aquarium fish, and see if anyone new, has a suggestion of Sid's real sp.
