Hello everyone!
I have a few Ricordia in my tank and they have been doing great. I have 2 Ricordia Floridas and 1 Ricordia Yuma. They are all sitting next to one another. I know they are from different regions. With the Floridas sting the Yuma or vice versa? How often should they be closing up? I notice they close up when the lights are off, is this normal? Thanks!
