Look man I said that it can be kept in an 20 gallon but that was an example so people themselves can do the math themselves and yeah they shouldn't be kept in an 20 gallon . And looked up at some major websites and did a lot of research on these fish and I know that they should be kept in groups of 5 or more. And I can't say that Wikipedia is wrong I'm sorry, the growth rate is slow my friends. Go use the internet read it yourself. As far as the keeping two. I told him to keep three because at least the dominate one wouldn't kill the other one. And if he can't then he shouldn't keep them might as well get an oscar
I have decided against the RBP. I think I have decided on a juvenile elongatus or rhombeus. I hear they grow fairly slow. So I can keep one in this tank for a few years and then will probably upgrade to a larger tank
Why not african cichlids or an oscar.
an african Cichlid tank will look lively
I am very confused as to how an oscar is OK for a 55 and not the RBP's.
Standard 55's are actually 13" wide rather than 12". I have had my two RBPs in a 55 for four years now, and they still are less than 11" today.
I can't fathom how a much bigger fish like a 15" oscar manages in a 13" wide tank wile a much smaller fish like a RBP somehow cannot turn around.
