dont know if anyone will like it but here are 2pics of one of my dora's; sorry about flash but I have had to take them in the dark as they are camera shy. I find these are perfect tank mates for my O's and are a little different to the normal plec or catfish. They are pretty indestructable also. I found one in the filter once he had been there we guess 3days I had serched the whole tank and all around. Submerged half in and out of water he had severe damage to top fin and body and stripped one of his side fins to the bone. But he wasnt phased and made full recovery. The shop keeper that I brought my O's from said he had accidentlly left one out of the tank over night as it was hidden in a rock ornament that he had left out to clean. He unlike most shopkeepers knew what he was selling and wanted to know what would be in with the oscars and what size tank I had. He agreed with me that dora's are pretty hardy and so here is my post 'for the DORA!'

nice looking fish, how big do they grow and how fast? What else are they known as?

There is already a thread about these I found it afterwards lol. But they can be down as humbug catfish, raphael catfish, platdoras and talking catfish as they make a hissing growling noise. grow about 25cm/10inches I have had one for about 15years and other I brought about 5years ago but it was an adult; they are both about 15cm/6inches and quite happy in with my O's.
