Hi,
jusz one ? Ok, if you can give hime a tankl on his own.
Asiatica are not tropical, I have mine between 14 and 22 °C al time feeding and beeing active. They spawned at 20-21°C last year.
Asiatica grow up to a foot long (30cm) and they have mighty jaws, that can even bite chuinks out fish they dont llike (my female did this to he husband,sche even ate him alive, his spine was completely without flesh for one inch).
So dont make the mistake keeping the fish too warm, and with others (even own species is hardly accepted!!)
They are great fun, when they stare at you from their tank.
And wobnderful fish to look at
Cheers
