RaZias Posted February 23, 2013 Share Posted February 23, 2013 I have normal Hissing Roach (G.Portentosa) and I am thinking on buying another variety of Hissing Roach (Elliptorhina javanica). Elliptorhina Javanica: --- I have two questions: 1- If I put both of them in the same vivarium will be there a problem ? (should I buy a separate one ?) 2- They might risk hybridizing and the Javenica variety will disappear because it´s recessive ? Quote Link to comment Share on other sites More sharing options...

thesavageprojects Posted February 23, 2013 Share Posted February 23, 2013 regardless of hybridization there is always going to be a risk that one sp. will out compete the other. if you want both to breed and thrive to there full potential, you will want a second cage.

RaZias Posted February 23, 2013 Author Share Posted February 23, 2013 The G.Portentosa will crush the Elliptorhina javanica WWF style. : ) I think a french seller sold me 2 Black Tiger Hissing Roaches (Gromphadorhina grandidieri) with 3 ordinary hissing roaches. The 2 black ones are agressive and fearless...one of them made a bull fight against an ordinary one....I think I understand what you mean by WWF.

MrCrackerpants Posted February 24, 2013 Share Posted February 24, 2013 Ya! That's what I mean. Once I caught a large male G.Portentosa repeatedly smashing itself into a small Elliptorhina javanica. The Elliptorhina javanica would run and the G.Portentosa would chase it and smash into it. I then separated them for good. The two different species will not hybridize.
