carpintas is fine but i may put the loiselli in a time out tank for a week and let the RTM settle in and maybe feel a little tougher , then reintroduce the loiselli.
They looked really nice in there... when I was there that loisellei only came out for a few minutes... the whole time it was out, it was hunting rtm.... nice tank by the way.
The males been coming out of the shell sometimes but darts back if anyone gets close.. female has not been seen. I'm sure she will pop out in a day or two.
