Wow Mattylou. You recognize a reference to an old Floyd song title. Poor Syd Barret hardly made it to that one. I hope some family of mice appreciate that when they may be holing up in my vinyl collection in the garage!
Leahis-I don't actually have the particular pair of rotkeil from the photo available for sale. Please refer to the stock list at my web page for actual fish available at any time.
I sent a PM to Jamie referring to the 'green severum' thing that may be worth a mention here.
I think both fish in those photos she posted are female appendiculatus.
The trade name 'green severum' is really obsolete and misleading.
Any Florida or Asian farmer who has severum and is not privy to a particular species name or origin of the fish will market the fish as 'green severum'. Those fish could be anything Heros and green. Much of the stock bred in commercial ponds cannot be traced to any particular lineage. In many cases, they were imported so long ago by who knows who and inadvertently or unknowingly crossed with other severums from other imports.
To the same point, the common name of 'green severum' will be used by, for example, a Guyana exporter indicating available species on a stock list.
So that 'green severum' = H. notatus.
A list featuring species offered for export from Manaus fish market may include 'green severum', but in this case, it's likely an efasciatus-type species.
The average Peru exporters' list may include 'redhead' or 'rotkeil' (I've recently see them marketed domestically as 'red neck'...) severum as well as 'green severum'. Here the distinction is interpreted 'green severum' = appendiculatus.
You see? If you're interested in the identity of your severum (or festivum, wild Scalare, etc.) it all depends on knowing the origin of the stock.
Speaking of appendiculatus, I carelessly forgot to post a pic in previous entry of an old wild male I kept and photographed at some time. Sorry about that old fish.
