Paratheraps syn size and sex

[smitty03281964]

You are not going to be able to sex them at 4 inches. They can get 16 inches.

Males tend to get a hump on their heads, be more colorful, longer fin extensions, and act like males

It takes them awhile to mature but like Buddha says, they can get every bit of 14" (or bigger) given the right conditions / time.

P. synspilum is now considered a junior synonym of P. melanurus...so they scientists now call them P. melanurus.

McMahan, Caleb D.; 2011; "Paraneetroplus synspilus is a junior synonym of Paraneetroplus melanurus (Teleostei: Cichlidae)"; Zootaxa; (n. 2833), pp. 1-14 (crc03297)

Here's the abstract of the paper (from Cichlid Room Companion): http://www.cichlidae.com/library/abstract.php?id=3297

So syns are now melanurus and they're both now Paraneetroplus genus?

Yes - according to McMahan...

I dont understand how that can be. They are clearly 2 different fish, with 2 clearly different looks. Hmmm, so same fish from different locals is reason for complete diff look. OK. I guess I can accept that.
