scaley Posted July 24, 2004 Share Posted July 24, 2004 Hoping someone can clarify some questions I have regarding the mazimum size of Green Terrors and Red Bellied Pacu. Reading through a number of websites I find some say GT's grow to 6-7 inches others say 10-11 inches(in the aquarium). That's a big difference. As for Red Bellied Pacu, my LFS tells me they grow as big as your hand, on the net most sites say they grow huge, 60-80 cm and one site said upto 110 cm. Are we talking the same fish here? There seems to be a lot of discrepencies in sizes for most American species. Link to comment Share on other sites More sharing options...

scaley Posted July 24, 2004 Author Share Posted July 24, 2004 Sounds like I may need to offload my Pacus before they take over the whole house then. Link to comment Share on other sites More sharing options...
Alex Posted July 24, 2004 Share Posted July 24, 2004 Red Bellied Pacus will easily reach 60-70cm in the home aquarium. Larger if given enough room. Black pacus will easily grow to 100cm. Link to comment Share on other sites More sharing options...
E4G13M4N Posted July 24, 2004 Share Posted July 24, 2004 From what we have been told from the wholesalers the RB Pacu's are supposed to be a dwarf variety??? I didnt know there was any, supposedly the fish that are being used to breed these are only around 7-8" and quite a few years old. Supposedly being bred in Melb.. What have others heard about these that are getting around. Link to comment Share on other sites More sharing options...

What have others heard about these that are getting around. The fish you are refering to are Metynnis maculatus spotted Metynnis, or spotted silver dollar, which have been getting around, these are not true red bellied pacus. True Red Bellied Pacus are Colossoma bidens Link to comment Share on other sites More sharing options...
catfishLegacy Posted July 24, 2004 Share Posted July 24, 2004 Yes, a well known wholesaler recently made a big mistake regarding these fish. Even though they knew the fish to be a Metynnis sp. (Silver dollar) they decided to give it the akward common name of: "Metynnis Red Bellied Pacu". And of course when this fish made it to the shops, they all decided to drop the Metynnis from the name. So yes, Alex is correct, the fish are Metynnis maculatus not Colossoma bidens... Although at the present time (as far as I can tell???) the taxonomy of Pacu looks like this: There are two species sold under the common name of "Black Pacu", Colossoma macropomum & Piaractus brachypomus. Red Bellied Pacu appear to be called Piaractus mesopotamicus. All wholesalers should do their research before labelling fish. The shops usually believe what they say is gospel, then they pass the mistakes on to the general public. Link to comment Share on other sites More sharing options...
