these are real beauties!
but the largest species of Paratilapia?
I really don't know; I have seen fully grown males of the "small spot species group" (wich includes the ones with the tiny blue spots) that had reached sizes more familiar with male Oscars or fully grown frontosa's
so truly huge.
what is the biggest Andapa around at the moment?
a completely different question: how do yours behave?
my current experience with Paratilapia is quite bad.
I've tried with different fish of different sizes and ages and despite the tanksize (315 gallons/1200 liters) it always ends with the male going in search and destroy mode on the female
even matching pairs that spawn turn vicious on each other in time and then it's all downhill from there
and the weird thing is; I have Paretroplus wich are perfectly well behaved to each other and the species are nourissatti (!), damii, maculatus and menarambo.
wich should be nasty, but they're not. the only one that gets bitten is yours truly cause he likes to handfeed and the fish have no fear at all
but Paratilapia over here seem to focus on just one thing and that is wholesale destruction of any speciesmember in the same tank.
right now I have 2 7 cm/2.5" "small spot east coast" and they can and will find each other to bite and rip, despite the huge menarambo's being the top honcho's in the tank.
