i just bought a pare of kribs and right away the male went in the cave and he has only come out a few times and only for a few seconds, but the female swam around right away but mostly around the cave that the male is in, but now she has gone into the cave with the male and has not really come out. so i was wondering if this is normal or if i should be worried because i have herd that the male and the female hardly ever go in the cave together and if they do it's only for a few seconds. any who, please help. thanks!
