Strange Kribensis Behaviour. SOLVED.

My female krib has piled up sand outside the entrance to the cave she's in, so much so I don't think that she could get out.

Is there any reason for this behaviour ?

Tank is due a clean and water change later in the week so don't want to do any harm if this is likely.

How long have you had her? Is there a male krib? What other tank inhabitants are there, if any? Also, what size of tank are they in?

Sorry for all the questions but this might help us get to the root of the problem / find a potential explanation (and solution, if necessary).

Female Kribensis defend and create little territories around the tank. they prepare caves for a male who will then choose a mate and spawn. I suspect she is preparing the area for an inspection by a male (If you have one), they produce a LOT of fry.

I have a pair and they haven't spawned since my clown loaches invaded their coconut.
hope this helps

They're preparing to spawn.

I assume she's in breeding condition (very colourful, very purple belly)?
