Kribenses Mating Behavior
 

I have four kribs, two female and two male. one set has paired up. There are 4 half shell coconuts for their caves. The paired kribs have picked out a shell and two days ago, I noticed a pile of gravel outside the entrance of the coconut shell. I do not want to disturb the shell or the pile.
Does this tell me the female laid eggs. The female is about 1-3/4 inches long and the male is about 2 inches long.
