Is there any reason that my kribensis have put so much sand in front of of the entrance of there cave. Usually they don't put much in front but this time they have created a mountain range In front of it and also they usually create two places for eggs where as this time they have only created one. Do you think this means they feel safer in the tank and there is a better chance of eggs. The first picture is the ones with a mountain range.
The second picture is off the other cave in there tank where no sand has been moved. Thanks for your help from Tom
